摘要
在文献 [2 ]中提出的自适应Smith预估控制方法中 ,经过仿真发现 ,当实际对象增益比估计模型增益大的时候 ,系统响应很慢 ,消除稳态误差的时间很长。经过深入分析和揭示问题的实质后 ,提出了另一种自适应律 ,该方法在没有影响原来控制效果的情况下 。
An adaptive Smith predictor system is proposed in paper.In the simulation results,when the scale of object is larger than the model's,the system response is very slow and the adjust time is very long.After researching the essential problem,another adaptive rule,which can not only improve response speed of the system but also will not effect the original control performance,is presented.
