Closed loop control of electro-pneumatic gearbox actuator

Abstract

This paper presents a servo control synthesis to design a Linear Quadratic (LQ) servo controller for electro-pneumatic gearbox actuator. In order to achieve nominal performance and meet stability specifications, the LQ synthesis is applied for controller design. The dynamic model of the electro-pneumatic gearbox actuator is built and linearized around a specific point. In this way, the controller can be designed to provide the track of the predefined reference signal and reduce the effects of the disturbances on performances. In the paper, the modeling, the control design strategy and the measurement results are demonstrated.
