Abstract

This paper presents a gray box approach for identifying physical parameters of an electromechanical actuator based on frequency response data. A feedforward and linear-quadratic regulator feedback controller was developed to control the EMCV actuator for soft seating. A repetitive learning controller was designed to enhance the control performance through cycle-to-cycle iterations. Experimental results achieved 0.61 m/s valve seating speed with 0.02 m/s standard deviation.
