| 摘 要： | 在液压伺服系统中,由受载体运动引起的输出误差严重影响施力系统的动态加载性能.本文提出了一种自适应逆控制方法来抑制并消除它.本方法以实际系统的输入输出信号为依据,实现系统建模,用被控对象传递函数的逆作为串联控制器来对系统的动态特性进行控制.该方法适用于实时处理的场合,并通过仿真来说明该方法可以较好地跟踪系统,并可以较好地抑制因位置扰动而引起的输出误差.

| Abstract: | An adaptive inverse control approach was proposed to eliminate the output error of a loading system caused by displace perturbation for the output error will make the system of bad robustness to unknown external load disturbance. Using the input and output signal, the method can model the system, and can control the dynamical property of the system with the inverse transfer function of the controlled object as the controller. The proposed approach can be used for real time implementation. Some simulations demonstrate the effectiveness of the approach in the eliminating the output error caused by displace perturbation. |
