Conference Proceeding: Second order sliding mode current controller for the switched reluctance machine
[show abstract] [hide abstract]
ABSTRACT: This paper presents a second order sliding mode current controller for the switched reluctance machine (SRM). This strategy is first analysed theoretically, then tested by simulation and on an experimental test bench. Dynamic, current ripples and robustness of this controller are discussed.IECON 2010 - 36th Annual Conference on IEEE Industrial Electronics Society; 12/2010 -
Conference Proceeding: Interconnection and damping assignment passivity-based control of a fuel cell system
[show abstract] [hide abstract]
ABSTRACT: This paper presents the design of a non-linear controller for an energy hybridization structure involving a hydrogen fuel cell with supercapacitors for applications with high instantaneous dynamic power. The design of the controller is based on the interconnection and damping assignment - passivity based control, and compared with a standard controller strategy based on proportional-integral controller. The stability properties, the number of degree of freedom and performances of both controllers are discussed.Industrial Electronics (ISIE), 2010 IEEE International Symposium on; 08/2010 -
Conference Proceeding: Second order sliding mode control of the moto-compressor of a PEM fuel cell air feeding system, with experimental validation
[show abstract] [hide abstract]
ABSTRACT: Fuel cells are electrochemical devices that convert the chemical energy of a gaseous fuel directly into electricity. They are widely regarded as potential future stationary and mobile power sources. The response of a fuel cell system depends on the air and hydrogen feed, flow and pressure regulation, and, heat and water management. In this paper, the study is concentrated on the air subsystem that feeds the fuel cell cathode with oxygen. An IP control, a RST regulator and a higher order sliding mode control, super-twisting algorithm, with variable gains, have been designed and validated experimentally to control the air flow of the moto-compressor system, composed of a DC motor driving a volumetric compressor of type piston, designed to feed a 500 W fuel cell with air. Experimental results show better performance with the sliding mode control, especially when dealing with a delayed air flow sensor response.Industrial Electronics, 2009.

Conference Proceeding: A reduced-order model and a higher-order sliding-mode control of the air supply system of a proton-exchange-membrane fuel cell with experimental validation

ABSTRACT: Fuel cells are electrochemical devices that convert the chemical energy of a gaseous fuel directly into electricity. They are widely regarded as potential future stationary and mobile power sources. The response of a fuel cell system depends on the air and hydrogen feed, flow and pressure regulation, and, heat and water management. In this paper; the study is concentrated on the air subsystem that feeds the fuel cell cathode with oxygen. Proceeding from a 4-th order model representing the air subsystem of a PEM fuel cell, a reduced 3-rd order model is presented. Simulations show that the relative error caused by this reduction doesn't exceed 0.5%. Experimental validation has been done on a 33 kW PEM fuel cell, for both 4-th and reduced 3-rd order models with less than 5% relative error. Additionally, a higher order sliding mode, super-twisting algorithm, with adaptive parameters has been designed and validated experimentally to control a permanent magnet synchronous motor (PMSM) that drives a volumetric compressor (double screw) designed to feed the 33 kW fuel cell with air.Advanced Electromechanical Motion Systems & Electric Drives Joint Symposium, 2009.
