摘要
舵机是导弹控制系统重要执行机构,其性能直接影响导弹命中精度;为了提高舵机系统跟踪精度与带宽,对直流无刷电动舵机系统分析、建模,设计经典PID控制器与指数趋近律滑模控制器;系统仿真表明:滑模变结构控制器在电动舵机控制方面具有优良的动态品质,满足舵系统指标要求。
Actuator was important executive mechanism of the missile control system, whose performance directly affected missile precision. To improve the tracking precision and bandwidth of actuator system, brushless DC motor actuator system was analyzed and modeled, PID control and exponential sliding model control were designed as well. Simulation shows that sliding model control make electric actuator system dynamic traits finely, and meet the design specification.
