摘要： 针对制导火箭弹惯性稳定平台位置伺服控制系统非线性、强耦合、外部干扰不确定以及系统参数摄动，传统PID控制无法满足该平台高精度位置控制的问题，提出模糊控制算法的策略，建立弹载惯性稳定平台模型，分析位置模糊控制器的原理，设计以位置偏差与其变化率为输入的惯性稳定平台位置控制器。所提控制算法应用于永磁同步电机驱动的惯性稳定平台系统，通过建模仿真表明，平台位置响应时间仅为25 ms、响应稳定且几乎无超调以及位置跟踪性能好，控制效果优于传统PID控制器，为弹载惯性稳定平台高精度位置伺服控制器的设计提供了参考。

Abstract: The inertial platform system of guided rocket is a strong coupling of multivariable nonlinear complex systems of existing external disturbances and uncertain system parameter variations. The traditional PID control has failed to meet requirements of the platform position control. To solve this problem, the proposed strategy used fuzzy control algorithm and then designed a fuzzy position controller owning two inputs of position deviation and its rate of change. The control strategy was applied to the inertial platform system drived by the permanent magnet synchronous motor. At last, constructed a simulation model. Simulation results showed that the platform position response was stable and almost no overshoot. Its response time is short just 25 ms and has good performance at location following. The proposed controller is better than conventional PID controller, which provides reference for the design of high precision of the inertial stable platform
