| Abstract: | In order to improve the continuous high precision and stable firing ability of an armed helicopter, this paper analyzes the load disturbance of the aerial gun servo system during continuous firing, and designs an improved load torque observer to observe the impact load of the system in real time. At the same time, the observed value is introduced as the feedforward compensation of the current loop. The non singular fast terminal sliding mode control is applied to the speed loop to ensure the finite convergence time of the system, reduce the chattering of the system, and improve the anti disturbance ability of the system. The simulation results show that the simulation model can correctly simulate the continuous firing state of the aerial gun servo system. The proposed control strategy can not only improve the steady state accuracy of the system, but also weaken the impact of impact load on the performance of the aerial gun servo system, which enhances the stability of the system. |
