【摘要】 为了提高弹用电动舵机的鲁棒性,采用了铰链力矩的舵机数学模型,从工程应用角度对模型中传递函数系数进行了适当修正,研究了一种基于离散滑模变结构控制器的弹用电动舵机控制方法,分析了离散滑模设计中的三个参数c,,εq的影响。经仿真验证,所设计的控制器不仅有较好的动态性能,而且所引起的0.3 V的抖动更利于克服舵机的死区电压。更多还原

【Abstract】 In order to improve the robustness of shell electromechanical actuators,the model with hinge moment is considered.The transfer function coefficient is corrected properly from the engineering viewpoint.A discrete sliding mode variable structure controller is designed for shell electromechanical actuator system.The influence of the control parameters c,ε,q is analyzed.The results of MATLAB simulation show that the controller can overcome the dead-time voltage and has a better dynamic performance.更多还原
