Low-Order Stabilizer Design for Discrete Linear Time-Varying Internal Model-Based System
IEEE ASME Transactions on Mechatronics, 2015Co-Authors: Xingyong Song, Pradeep Kumar Gillella, Zongxuan SunAbstract:This paper focuses on the low-order stabilizer design for linear time-varying (LTV) internal model-based system in the Discrete time Domain. While an output feedback gain injection-based stabilizer was proposed for continuous LTV systems in previous work, the synthesis in Discrete Domain has its unique challenges, and the approach formulated in the continuous Domain cannot be directly applied. In this paper, the stabilization for LTV internal model-based control in the Discrete setting is formulated, its challenges are revealed, and two control synthesis methods are presented. The merits and limitations of both approaches are discussed and then further studied through simulation and experimental investigations.

Investigation of time-varying internal model based control for camless engine valve actuation
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012Co-Authors: Pradeep Gillella, Xingyong SongAbstract:This research focuses on the tracking control design for a camless engine valve actuator during engine speed transients. The cyclic but aperiodic valve reference signal to be tracked can be modeled using two different methods, i.e., as a combination of frequency varying sinusoids in the time Domain or as a repetitive (periodic) signal in the rotational angle Domain. The recently developed time-varying internal model based controller is ideally suited for both the approaches. Investigation of the continuous time and Discrete Domain implementations uncovers some unique characteristics resulting from the time-varying nature of the system which favor working in the Discrete Domain. A quantitative analysis comparing various performance metrics for the different approaches of modeling the reference signal helps highlight the relative advantages of each method. Finally, experimental results from a prototype camless engine valve actuation system help validate the overall effectiveness of the proposed approach.

Transforming variable transport delays into fixed ones: An application to a conveyor belt problem
2018 Annual American Control Conference (ACC), 2018Co-Authors: Thomas Laurain, Jimmy Lauber, Zsófia Lendek, Reinaldo M. PalharesAbstract:This paper presents a systematic methodology to deal with variable transport delays by constructing a new Discrete Domain where the delay becomes fixed (a difference of samples). The Euler transformation is used to change from the continuous-time Domain to this special Discrete Domain depending on the same variable as the transport delay. After this transformation, the model becomes nonlinear and the Takagi-Sugeno fuzzy representation is used to handle the nonlinearities. To highlight and illustrate the efficiency of the proposed methodology, an LMI based controller design is used to control a conveyor belt with variable transport delay.

FUZZ-IEEE - Dual clutch torque estimation Based on an angular Discrete Domain Takagi-Sugeno switched observer
2016 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2016Co-Authors: Rémi Losero, Jimmy Lauber, Thierry Marie Guerra, Pascal MaurelAbstract:× Nowadays, the dual clutch transmission is tending to be generalized because of the high yield of this kind of gearbox with sprockets. The dual clutch transmission also allows gear shifting without torque breaking. These kinds of transmissions are usually controlled in torque. To exploit all of the capacities of this technology in term of comfort and driving pleasure, accurate information of both clutch torque is mandatory. Further, the clutch torque cannot be measured on vehicle because of cost and packaging reasons. This paper proposes a technical solution of the clutch torque estimation in the dual clutch control framework. The estimation is based on an angular Discrete Domain Takagi-Sugeno switched observer and shaft torsion estimation from encoder sensors with a virtual teeth adding method. The methodology permits to obtain very interesting simulation results of clutch torque estimation on a complete vehicle simulation platform.
