自适应MAC的改进算法

Imprevement Algorithm of Self-adapted MAC

针对具有欠阻尼特性的被控对象，提出了自适应MAC的改进算法。改进算法采用一种紧凑模型描述对象单位脉冲响应序列，可使截取为内模的对象单位脉冲响应有限序列长度大大减小。因此，内模在线辨识及MAC的在线计算量显著减小，大大提高了自适应MAC的实时性。

This paper presents an driprovement algorithm of self adapted MAC for conbolled system with under - damping characteristics. By using a compact model to describe unit pulse response time - sequence of the controlled process, the number N of leading terms of such a sequence,togather with the on - line internal model identthcation and MAC computahon can be greaily reduced while the prachcality of self- adapting MAC being improved.
