一类模型跟随自适应控制方法及其在高响应电液位置伺服系统中的应用

A New Model-Following Adaptive Control Method and Its Applications in a High-Response Electrohydraulic Position Servo System

从零极点配置结构图出发,导出了一类模型跟随自适应控制方法。该方法能够有效地处理含纯时延环节的过程的控制问题,理论上不要求被控过程与参考模型具有相同的零点。并讨论了该方法在高响应电液位置伺服系统中的应用。实验结果表明,该方法对于低频信号(方波及正弦波)具有相当高的跟踪精度。

A new model-following adaptive control method is proposed in this paper, in which the transmission time-delay is considered, and the new method does not theoretically require that there be the same zeros for the model reference model and the controlled plant. The applications of this method in a High-Responce Electrohydraulic Position Servo System is discussed, and the experimental resuits show that the control accuracy to low frequency signals is effectively augmented.
