摘　　要：建立了飞机仿真器航道罗盘伺服系统数学模型,选择直流电动机作为系统的执行元件,采用滑模控制(SMC)设计位置环控制器,重点讨论了控制参数的选取。仿真和实验结果表明,与直接采用LQR方法设计的控制器相比,结合变结构控制选取的控制器具有较强的鲁棒性能,能够满足系统的快速定位要求。The mathematic model of flight simulator path compass servo system is founded.The DC motor is chosen to be the executing device for system.The Sliding Mode Control is adopted to design the position controller,and the choice of controller parameters is discussed chiefly.The simulation and experiment results show that,compared with the controller designed by LQR method separately,the controller combining with the variable structure control has stronger robust performance,and it can satisfy the request of quick positioning.
