摘要
本文给出的MRACS,其结构较之HangC C.和Tang H S·提出的新结构方案(1981)和吴士昌等三人提出改进的新结构方案(1985)更为简单,但在功能上是等价的。本系统不但少用了一组滤波器,而且省去了线性补偿器,从而略去了对线性补偿器系数的选取。基于波波夫超稳定理论,求出了保证系统全局渐近稳定的参数自适应律。仿真结果表明,跟随效果良好。
This paper puts forword a kind of structure of adaptive contirol system.This structure is simpler than others,for it not only saves a group of state variable filter but also a linear compensator. The result of simulation proves that the quality of plant following reference model is satisfactory.
