A Design Method of Optimal Deadbeat Servo System with Two-Degree-of-Freedom

Abstract

In this paper, we propose a new design method of optimal deadbeat servo system with two-degree-of-freedom. In this design method, the desired value tracking characteristics and disturbance rejection characteristics can be performed by different compensators.
The optimal deadbeat control signal which minimizes the quadratic performance index for control signal and deviation can be easily obtained from the matrix computation using sampled data of the step response of the system. Then, the deadbeat controller can be designed by using the control signal.
We show our simulation results with several numerical data to demonstrate the effectiveness of the present method.
