| 摘 要： | 对CMAC神经网络的工作原理进行了简要讨论,针对主动磁轴承具有本质不稳定性和高度非线性动态特性的特点,提出了一种基于CMAC神经网络的非线性控制方案以改善系统的特性.对某单自由度磁轴承的仿真研究表明,CMAC神经网络控制器抗扰动能力强,同时其他控制品质也比传统PID控制器好.

| Abstract: | The principle of CMAC neural networks is discussed briefly.Aiming at the highly nonlinear and naturally unstable dynamics of active magnetic bearings(AMB),a nonlinear controller based on CMAC neural networks is proposed to improve system dynamic performance.The simulation results of a single-degree-of-freedom AMB system show that the proposed controller has good disturbance rejection ability;and other control performance is also much superior to the traditional PID controller. |
