| Abstract: | Put forward a parameter optimal method which H-infinity controller with prescribed close-loop pole region is proposed based on control theory. In design of the method we synthetically consider the index of H-infinity and dynamic performance,and surmount the problem of unstable controller in normal H-infinity design method. Experiment result shows that the method have the advantages of simplified computation,good realizability,strong robustness and good closed-loop dynamic performance, and low sensitivity to model parameter change. |

| Keywords: | H-infinity control stable region parameter optimizing robustness |
