| 摘 要： | 本文对被控对对象不稳定的非最小相位系统,应用使输出误差和加权输入的H~2空间范数极小,提出一种模型参考自适应控制算法.避免由于被控对象弱阻尼区零点和闭环系统极点对消使控制输入产生大幅值的跳动,克服性能指标中要预先选择加权函数存在的困难.算法较为简便,可以配置闭环零极点.仿真例子说明了良好的稳定性能和跟踪性能.

| Abstract: | In this paper,an adaptive control algorithm obtained by minimizing the H~2-norm of the output error and the weighting input,is presented.This algorithm can deal with nonminimum-phaseor unstable systems.For this reason,it is necessary,to avoid the cancellations of sta- ble plant zeros in the poorly damped region by the closed-loop system poles,to prevent a large ripple con- trol input,and to overcome the difficulty by an advanced choice of weighting function.The algorithm is a relatively simple method,which can be used to dispose the closed-loop system zeros-poles.Simulation ex- amples are presented to show the stability and the good tracing behaviour. |
