SLIDING MODE AND ACTIVE DISTURBANCE REJECTION BASED COMPOSITE CONTROL METHOD OF TANK GUN CONTROL SYSTEM

摘要

A sliding mode and active disturbance rejection based composite control method of a tank gun controlling system can improve the dynamic shooting performance and stability of the tank gun control system. The method comprises: firstly, building a tank gun high-low stabilizer control model; designing a sliding mode variable structure switching function and a control law thereof according to the control model; designing an active disturbance rejection controller according to the control module; and finally designing a composite controller of the tank gun controlling system according to the switching function, the control law and the active disturbance rejection controller. The active disturbance rejection controller comprises a tracking differentiator, an extended state observer and a nonlinear feedback control law.
