Abstract :
asymptotically stableIn this paper we derive a controller for an electropneumatic clutch actuator system. On/off valves are being used as control valves, and this impose restrictions on the control design. We show that the system with the derived controller are asymptotically stable in the whole region of operation of the system, and we discuss robustness of the design. The presented simulations verify the results of the paper.
