摘要
电流环、速度环、位置环三环控制在交流伺服控制系统已广泛使用。它能精确控制电机的转动,从而达到很高的控制精度。然而在有干扰运动的情况下,此种控制方式很难达到控制精度。因此,本文研究了基于动力学前馈的控制系统。通过仿真结果可以明显看出,动力学前馈的控制系统能够较好的消除外界的干扰,满足其性能要求。
Current loop, speed loop and position loop have been widely applied in AC servo control system. By u- sing these loops, rotation of motor can be controlled precisely to achieve high control accuracy. However, in case of interference, high control accuracy is difficult to achieve by using of such control system. A control system based on dynamics feed -forward is studied. Simulation results prove that the control system based on dynamics feedforward can eliminate external interference more effectively and meet performance requirements.
