由于机载稳定平台工作中会受到飞机振动、风阻力矩等外界干扰因素的影响，导致探测设备出现指向不稳定、跟踪精度低等问题。研究了滑模控制算法在航空稳定平台上的应用，利用 Matlab／Simu-link 建立了永磁同步电动机伺服系统的滑模控制仿真模型，通过仿真和在试验系统上测试，实验结果表明滑模控制算法与普通 PI 算法相比较，不容易受到外界干扰力矩的影响，具有较好的鲁棒性，在相同外界干扰的情况下可以保持较好的跟踪精度。

Because of the vibration of aircraft and the moment of wind resistance,the airborne stabilized platform can’t keep the high tracking accuracy of the detection equipment onboard.In this paper,the slide mode control(SMC)method is used in the permanent magnet synchronous motor(PMSM)servo system. Compared with other control methods,the simulation and test results show that,the proposed method can improve the ability of anti-interference for the servo system.
