Abstract :
This paper studied the design of fully-digital electro mechanical servo system. In this paper a set of servo system for the rudder is designed at the high accuracy position request. A new ADRC (active disturbance rejection control) is analyzed in this paper. Then the ADRC system of servo system was designed. Through a testing in the simulation of MATLAB, the results show that the ADRC system has favorable characteristics of dynamic celerity, static stability, steady precision, high robustness to the variation of load.
