Pollutant Reduction of a Turbocharged Diesel Engine Using a Decentralized Mimo Crone Controller
Fractional Calculus & Applied Analysis, 2015Co-Authors: Abderrahim Lamara, Patrick Lanusse, Alain Charlet, Guillaume Colin, Dominique Nelson Gruel, Yann ChamaillardAbstract:This paper presents a frequency-domain methodology for Robust SystemControl design, and its application in airpath Control of a real turbocharged Diesel engine with intake throttle and exhaust gas re-circulation System. The objective is to find a Robust Control-System which reduces pollutant emission. The three inputs (throttle, wastegate and EGR valves) and two outputs (airflow and boost pressure) of the airpath make the System complex. AMulti InputMulti Output (MIMO) fractional order approach called CRONE (French abbreviation which means Robust Control of a non integer order) is used to design a non-square Control-System for this non-linear plant. Firstly, a multisine signal is used for the System-identification, the airpath inputs are excited around all operating points in order to find a linear model of the plant. Then, the frequency responses of a defined nominal plant and experimental plant are taken into account to design the MIMO Control-System using the CRONE shaping approach which permits to maintain performance and Robust stability around a wide set of operating points. Finally, pollutant emission results from a driving cycle in test-bench show the relevance of the proposed approach.

Decentralized Robust Control-System for a non-square MIMO System, the air-path of a turbocharged Diesel engine
2012Co-Authors: Abderrahim Lamara, Patrick Lanusse, Guillaume Colin, Yann Chamaillard, Alain CharletAbstract:The targeted purpose here is the Control of a nonlinear and non-square System with three inputs and two outputs in order to reduce soot and greenhouse gas pollutants. In this paper, a non-square multivariable Controller for the air-path System of a turbocharged Diesel engine is proposed. The Controller is designed using the CRONE (Commande Robuste d'Ordre Non Entier) Control-System-Design approach to maintain performance and Robust stability for a wide set of operating points. In this research, we focused on the multi-input multi-output System identification problem, and test-bench data were processed to find a nominal linear model. The Controller was then designed via an open-loop transfer function optimization. Finally, simulation results from a simulation model show the performance of the proposed Control-System.

vibration Control of a suspension System via a magnetorheological fluid damper
Journal of Vibration and Control, 2002Co-Authors: Chun Yu Lai, Weihsin LiaoAbstract:Semi-active Control Systems are becoming more popular because they offer both the reliability of passive Systems and the versatility of active Control without imposing heavy power demands. It has been found that magneto-rheological (MR) fluids can be designed to be very effective vibration Control actuators. The MR fluid damper is a semi-active Control device that uses MR fluids to produce a Controllable damping force. The objective of this paper is to study a single-degree-of-freedom suspension System with an MR fluid damper for the purpose of vibration Control. A mathematical model for the MR fluid damper is adopted. The model is compared with experimental results for a prototype damper through finding suitable model parameters. In this study, a sliding mode Controller is developed by considering loading uncertainty to result in a Robust Control System. Two kinds of excitations are inputted in order to investigate the performance of the suspension System. The vibration responses are evaluated in both ti...
