| 摘 要： | 纯滞后特性的存在极大地影响着具有预置稳定度的ＬＱ（ｌｉｎｅａｒｑｕａｄｉａｔｉｃ）状态调节器的稳定裕量。通过Ｐａｄｅ逼近法对纯滞后环节降阶处理，将纯滞后对系统的影响反应到ＬＱ性能指标中，通过有限维状态反馈，实现了纯滞后对象的ＬＱ次优控制。仿真结果表明，该方法可以获得很好的过渡过程特性，对滞后时间变化的鲁棒性极好。

| Abstract: | The exist of time delay influences the stable margin of LQ state regulator with prescriped degree of stability serionsly.So the link with time delay is trausacted by simplified its model with pade method in this paper.Thus we can realize the suboptimal control through the feedback of limited states.The simuulation result shows that good transient character can be obtained,and robustness to time delay is very good. |
