摘　　要：针对简易制导火箭弹电视位标器在极速状态下系统响应的快速性和平稳性问题,提出了基于指数趋近律的滑模控制(SMC)复合PID的控制算法,建立了基于永磁同步电机位标器的数学模型,设计了滑模控制器,并进行了复合控制算法的仿真与分析。结果表明:系统采用复合的控制算法克服了传统PID控制算法工作模式下系统转速和力矩输出波动大、对负载扰动敏感、系统抖振严重的不足之处,且复合算法能够显著提高系统的动态品质。In view of the problems of rapidity and stability of system response that resulting from the TV gauge device of simple guidance rocket projectiles in the extreme conditions, a control algorithm of the sliding mode control （SMC） composite PID based on The exponential reaching law was presented. Firstly, the mathematical model of gauge device based on PMSM was established. Secondly, the sliding mode controller was designed. Then the composite control algorithm was simulated and analyzed in this paper. It turns out that system adopting the composite control algorithm overcomes the shortcomings of traditional PID control algorithm in which the system speed and output torque fluctuation are big and the system is sensitive to load disturbance, and the system chattering is serious. The composite control algorithm can significantly increase the dynamic quality of the system.
