英文摘要：

According to the design problems of output feedback for general periodically tim-varying descriptor systems,by using the analysis methods of descriptor Lyapunov inequality and linear matrix inequality（LMI） and by introducing the feedback into the general periodically time-varying descriptor systems,an tribe controllers of output feedback was obtained for this kind of systems to be admissible and satisfy performance index of H∞ control.The conclusions of output feedback research achievements are natural extend from descriptor systems to the general periodically time-varying descriptor systems.Finally,a numerical example was given to illustrate the effectiveness of the approach.
