An adaptive robust control method is proposed to solve a series of complex nonlinear problems in the gun control system during the rapid movement of the tank. Combining the characteristics of intelligent optimization of self-parameters in adaptive control and the stability of robust control, a disturbance observer which can accurately measure the disturbance term in real time is designed and added to the control strategy, so as to accurately compensate the disturbance. The simulation results show that the control strategy can improve the anti-interference ability and stability of the gun control system, and effectively improve the firing accuracy when the tank is moving.
