Abstract

This paper presents a nonlinear controller which is called auto-disturbance rejection controller (ADRC) applied to a gyro stabilized system. The mathematical model of the servo loop of the gyro stabilized system is discussed. The basic theory of the ADRC is introduced. According to the mathematical model, the parameters of ADRC for the servo loop is designed. The results of simulation show that not only the dynamic and static characteristics of the system can satisfy the performance requirements, but also the control effect of ARDC is better than the effect of the classical PID controller.
