将广泛应用于机器人手臂控制等其它柔性控制系统的输入指令整形减振技术移植到转台应用中, 对这种技术的减振原理进行了详细的介绍, 并对输入指令整形器的设计方法、对系统参数变化的鲁棒性进行了探讨, 最后以M254 -90A电动三轴飞行仿真转台的中框为对象进行了仿真, 仿真结果表明, 输入指令整形器以前馈的形式作用于飞行仿真转台的控制系统时, 既不影响系统的稳定性, 又可以很好地抑制飞行仿真转台的机械谐振 Transplanting the input command shaping vibration reduction technology which is widely used in other flexible control systems such as robot arm control to turntable application, introduces the damping principle of this technology in detail, and introduces the design method of input command shaper, The robustness of the system parameters is discussed. Finally, the middle frame of the M254 -90A electric three-axis flight simulator is simulated. The simulation results show that the input command shaper acts on the control of the flight simulator System, it does not affect the stability of the system, but also can restrain the flight simulation turret mechanical resonance
