摘　　要：随着技术的发展,新型火炮武器作战系统对随动控制有了更高的要求,要求其不仅要有较好的抗扰动能力,还要有更好的控制精度。在此应用背景下,提出了基于观测器的改进滑模火炮随动控制方法,利用观测器对系统的扰动进行估计和补偿,用以提高系统的抗扰动能力;改进滑模控制方法来提高系统的控制精度,通过选用幂函数代替传统滑模控制中的符号函数,来抑制系统的抖振,用于提高系统的控制性能。并且利用MATLAB/Simulink仿真工具,搭建上述的改进滑模控制器,通过与传统PID控制方法的仿真对比,可以看出改进滑模控制器应用到火炮的随动系统中,具有较好的抗扰动能力和优良的控制效果。With the development of technology,the new artillery weapon combat system has higher requirements for servo control,which requires it not only to have better anti-disturbance ability,but also to have better control accuracy.In this context,an observer based improved sliding mode artillery servo control method is proposed.The observer is used to estimate and compensate the disturbance of the system to improve the anti-disturbance ability of the system,and the sliding mode control method is improved to improve the control accuracy of the system.The buffeting of the system is suppressed by using power function instead of the sign function in the traditional sliding mode control.And it is used to improve the control performance of the system.MATLAB/Simulink simulation tool is used,the abovementioned improved sliding mode controller is built.Through the simulation comparison with the traditional PID control method,it can be seen that the improved sliding mode controller applied to the servo system of artillery has better anti-disturbance ability and excellent control effect by the simulation comparison with the traditional PID control method.
