摘要
提出一种基于Smith预估器的H∞ 鲁棒控制器的设计方法 .该方法用Smith预估器巧妙地将时滞过程的鲁棒性能问题转化为无时滞过程的鲁棒性能问题 ,简化了分析和综合 ,避免了时滞的分式近似 .理论分析及仿真结果表明该方法有效地克服了时滞 ,使系统的鲁棒性能得到了明显改善 .
A design method of H ∞ robust controller based on Smith predictor is presented, where the robustness problem of time delay process is ingeniously shifted into that of delay free process, so that the analysis and synthesis are simplified and the fractional approximation of time delay is avoided. Both theoretical analysis and simulation result show that the method presented can effectively deal with the time delay and remarkably improve system robustness.
