摘要
本文只用输入输出测量值设计了一种全局稳定离散模型参考自适应控制系统。与文献[2]相比,作了三点改进:少用了一组滤波器;将可测负载扰动L(k)的未知增益项扩展成多项式形式;去掉了控制输入up(k)表达式中存在的可调参数_0(k)的除数项。
A globally stable discrete model-reference adaptive adaptive control system design using only input and output measurements is presented. It made three improvments for literature [2]: reduced a group of state variable filters; extended the unknown gain term for the measureable load disturbance L (K) into a polynomial version; removed the denominator of adjustable parameter b_0 (K) in the expression of control input Up(K).
