| 摘 要： | 提出了一种采用CMAC神经网络的自学习控制器，以解决具有参数不确定和时变外扰动的电液位置伺服系统的高精度控制问题，该控制器采用动态误差作为CMAC的激励信号，从而使基于CMAC的控制器跟踪连续变化的信号成为可能。仿真结果证明了该控制器不仅是有效的，而且具有很强的鲁棒性。

| Abstract: | A learning controller based on CMAC neural network is proposed to achieve high precision control for an electrohydraulic position servo system in the presence of uncertainties and time-varying load disturbance. The proposed controller adopts the dynamic and desired errors of the system as input vectors to the CMAC. This feature qualifies the CMAC-based controller to track continuous variable signals such as sinusoidal wave. The simulation results show that the proposed controller is not only effective, but also good of robustness. |
