Abstract :
Aims at the nonlinearity such as friction and varieties of system parameters and unmodeled dynamics in azimuth gun control system of tank, in order to improve the low speed performance and anti-interference ability, the strategy of LADRC is proposed. Considering nonlinearity and non-model dynamics as a composite disturbance, the math model of azimuth gun control system is established firstly, then the improved LADRC controller is designed, finally, the method is verified by simulation. The results show that the method is superior to the classical PID control. The low speed performance, anti interference ability and tracking accuracy of gun control system are greatly improved. Besides, it also has fast response, simple parameter adjustment, and only one parameter is adjusted to obtain good performance. The method provides a new approach for the controlling problems of tank gun control system.
