Abstract
This paper presents a robust servo control synthesis to design a position controller for an electro-pneumatic Clutch By Wire (CBW) system. In order to achieve high reference tracking performance and meet stability specifications, the H ∞ synthesis is applied for controller design. The nonlinear dynamic model of the CBW system is shown and transformed into an appropriate coordinate system. Then exact linearization is performed via state feedback. In this way, the controller can be designed to provide the track of the reference signal with predefined dynamics and reduce the effects of the disturbances on the performance using the H ∞ method. Moreover a controller order reduction is proposed based on the Hankel singular value based model order reduction. In order to handle the saturation of the control signal a high gain anti-windup is applied. Finally the simulation results are demonstrated and evaluated.
