| 摘 要： | 本文针对广义最小方差自校正控制存在的问题,提出了利用双重切换控制消除稳态误差的新方法,使控制系统的动特性有所改善,并消除了稳态误差。对时变滞后系统,本文利用极小化二次型目标函数的方法实现对时变滞后的在线递推估计,尤其对大滞后系统及二次型目标函数为多极值情况,本算法简单快速且实用.实时仿真和应用结果表明,本算法在许多方面优于广义最小方差方法。

| Abstract: | An improved self-tuning control scheme with servo-tracking and time- delay identification is proposed. By means of duplex switohing control,ibis method oan improve the system dynamic characteristics and eliminate the steady state error.In this paper the variable delay time is identified and the para- meters are estimated recursively by using the minimization of quadratic form target function Q(.).It is a simple,fast and practical algorithm for systems with large time delay and for Q(.)with multi-extremum.Simulation and app- lication has indicated that the proposed method has more satisfactory perfor- mance compared with generalized minimum variance algorithm. |
