First, the design problems of H2 and Ho controllers are discussed, respectively. Secondly, when there are partial actuator faults for the descriptor system, controllers with H2 and H∞ performance are designed, respectively. Finally, a numerical example is given to illustrate the design procedures and their effectiveness.展开更多

文摘The design problem of a reliable observer-based controller with mixed H2/H∞ performance for descriptor systems is discussed using linear matrix inequality (LMI) approach. First, the design problems of H2 and Ho controllers are discussed, respectively. Secondly, when there are partial actuator faults for the descriptor system, controllers with H2 and H∞ performance are designed, respectively. Finally, a numerical example is given to illustrate the design procedures and their effectiveness.
