Integration of PD-type Iterative Learning Control with Adaptive Sliding Mode ControlProportional-Derivative type Iterative Learning Controller (PD-ILC) is combined with an Adaptive Sliding Mode Controller (ASMC) using a plug-in structure to a rotary pendulum. The ASMC adaptation law is used to update a switching gain of sliding surface in Sliding Mode Control (SMC) controller. The proposed hybrid controller stability and convergence are mathematically shown and then experimentally demonstrates using two-degree-of-freedom (2-DOF) Quanser\textcopyright~QUBE$^TM$~Servo 2 Rotary Pendulum. Results illustrate that adaptation law helps the controllers to achieve higher accuracy tracking performance compared to the classic SMC controller. Based on the experimental results, the hybrid control of PD-ILC and ASMC has faster and more accurate tracking results than ILC controller indicating the combined controller has better performance than the individual controllers.

NVO peak pressure based in-cycle control for HCCI combustion using direct water injectionHomogeneous Charge Compression Ignition (HCCI), is a low temperature combustion method, which can significantly
reduce nitrogen oxides (NOx) emissions compared to current lean-burn spark ignition engines. The lack of direct ignition
control leads to high cyclic variation with HCCI combustion. A fully variable electromagnetic valve train is used to
provide the required thermal energy for HCCI through internal exhaust gas recirculation (EGR) using negative valve
overlap (NVO). This leads to an increase in the cyclic coupling as residual gas and unburnt fuel is transferred between
cycles through EGR. To improve combustion stability an experimentally validated feed-forward water injection controller
is presented. Utilizing the low latency and rapid calculation rate of a Field Programmable Gate Array (FPGA) a real-time
calculation of the cylinder pressure and the controller is implemented on a prototyping engine controller. The developed
and experimentally tested controller relates the upcoming combustion phasing to the peak NVO pressure. This control
strategy aims to prevent the early rapid combustion following combustion during the NVO period by using direct water
injection to cool the cylinder charge and counter the additional thermal energy from any residual fuel that burnt during
the NVO period. By cooling the trapped cylinder mass the upcoming combustion phasing can be delayed to the desired
setpoint. The controller was experimentally tested showed slight improvement in the combustion stability as shown by a
reduction in the standard deviation of indicated mean effective pressure and reduced pressure rise rates. University of Alberta | Publication | 2019-05-16 | David Carl Gordon, Koch, C., "Christian Wouters", "Bastian Lehrheuer", "Stephan Pischinger", "Maximilian Wick", "Jakob Andert" |

In this year, again over 90 participants from 13 different countries visited the conference in Aachen.
In 19 technical presentations and additional plenary speeches of Prof. Christian Schwarz (BMW Group), Prof. Per Tunestål (Lund University) and Prof. Gregory M. Shaver (Purdue University), the latest theoretical and application driven developments for the control of next generation combustion engines were presented. During the two conference days, varied topics were expounded.
Prof. Christian Schwarz showed detailed life cycle analysis of different electrified powertrains and highlighted that improved combustion engines can significantly contribute to a reduction of CO2 emissions. The use of e-fuels couples the production of electrical energy to the transport sector combines benefits like peak shaving in the energy grid with low-CO2 transport. Prof. Per Tunestål showed an outstanding presentation how combustion control can act as an enabler for clean combustion engines. Also the third keynote from Prof. Gregory Shaver focused on low emission engines, but more on the Diesel side. He showed very clearly that improved control methods could help to keep the exhaust aftertreatment system in the right temperature range.The dinner took place at the restaurant LivingRoom close to the historical city hall.

A Variable-Potential Amperometric Hydrocarbon SensorUsing the understanding of an inexpensive production NOx sensor, the operating parameters are changed to enable hydrocarbon measurement using the same sensor. A limiting-current-type amperometric hydrocarbon sensor for rich conditions (in the absence of O2) is developed in this work. To do this, an inexpensive three-chamber amperometric sensor with three separate electrochemical cells is parameterized to measure propane concentration. The sensor is tested using a controlled sensor test rig at different propane concentrations. The inputs to the sensor electrochemical cells have been modified to determine the best HC measurement parameters (HCMPs) for measuring propane at different concentrations. First, the transient performance and stability of the sensor are optimized by changing the sensor temperature, the reference cell potential, and the stabilizing cell potential at a high propane concentration (5000 ppm - balanced with nitrogen). Over the range tested, the sensor has the longest stable output duration at the temperature of 1009 K, the reference cell potential of 0.67 V and the stabilizing cell potential of 0.45 V. Using these sensor inputs for sensor temperature, reference cell potential and stabilizing cell potential, the sensor steady state behavior is studied to find the diffusion-rate-determined operating region. The sensor is shown to have a linear sensitivity to propane concentration from 0 to 3200 ppm. Finally, the sensor response time to different step changes from 0 up to 5000 ppm propane concentration are studied. It is shown that propane stepsize does not have a significant effect on the sensor response time. Consequently, using the working principles of an existing production amperometric NOx sensor and changing the sensor operating parameters, an amperometric hydrocarbon sensor that works in diffusion rate determining operating region is developed.

In-cycle control for stabilization of homogeneous charge compression ignition combustion using direct water injectionHomogeneous charge compression ignition offers a high potential for the reduction of CO2 and NOx raw emissions; however, its use entails problems that are associated with low combustion stability, especially at the limits of the operating range. The recirculation of exhaust gases inside the combustion chamber by using a negative valve overlap leads to a strong coupling of consecutive cycles. The cyclic coupling induces phases of unstable operation after the occurrence of stochastic outlier cycles with misfire or incomplete combustion. These unstable phases are marked by reduced efficiency and increased emissions. Two in-cycle closed-loop control algorithms, which focus on the heat release in the intermediate compression, are presented in this article. To control the combustion process, direct water injection is used to ensure a direct influence on the temperature level in the combustion chamber; subsequently this influences combustion phasing. The decoupling of consecutive cycles serves to reduce deviations in the indicated mean effective pressure and crank angle position of 50% mass fraction burned. To develop a suitable controller, a first-order autoregressive model of homogeneous charge compression ignition combustion is split into intermediate compression and main combustion phases. Moreover, unstable sequences are analyzed in the time domain to identify appropriate in-cycle control concepts. The control concepts are developed based on the heat release in the intermediate compression as a strong correlation factor for consecutive cycles. To realize fast control interventions, a real-time cylinder pressure analysis as well as the control algorithms are implemented on a field-programmable gate array. The control algorithms are validated on a single-cylinder research engine and compared with conventional operation without in-cycle control. Results show a significant increase in the stability of combustion phasing and load by means of in-cycle control.

Phenomenological model of a solid electrolyte NOx and O2 sensor using temperature perturbation for on-board diagnosticsAbstract Amperometric \NOx\ sensors are increasingly used in automotive industry to meet the stringent emission measurement regulations. These sensors measure O2 and NOx concentration using two different sensing cells. In this work, a physics-based model was developed and then employed to predict the sensor output for oxygen as a function of sensor temperature and oxygen concentration. A temperature perturbation method was also developed based on the model to calibrate the sensor output with respect to oxygen concentration. The model accurately matched the experimental results for steady state and transient conditions. A two step sensor diagnostics procedure based on the sensor temperature perturbation method was then proposed. The first diagnostics step evaluates the sensor output to check if it is within the acceptable range. The second diagnosis step checks the plausibility of the sensor output based on the physics based model and temperature perturbation. A self-calibration procedure was also implemented inside the diagnostics procedure using temperature perturbation at engine-off. This self-recalibration only requires an external relative humidity measurement. University of Alberta | Publication | 2018-04-15 | Masoud Aliramezani, Koch, C., Ron Patrick |
