Therefore the research of descriptor system is of farreaching significance This thesis discusses the problem about the passive control of the descriptor systems. The system's models are more generalized than others existing literatures. Main content as follows:First of all, the main background and the recent development are described for the descriptor systems. The passive control and the research method for the descriptor systems are also introduced.Secondly, the problem of observerbased robust passive control of descriptor systems with timevarying delay is discussed. Utilizing the methods of Lyapunov function, the sufficient condition for the generalized quadratic stability and the robust strictly passive of the closedloop system are given, moreover, the observer gain and the controller gain are constructed.Thirdly, as for a class of normbounded uncertain TS fuzzy descriptor systems with timedelay, the problem of observerbased passive control was studied and the sufficient condition for strictly passive of the closedloop system are given.At last, focuses on the timedelay descriptor systems, utilizing the methods of Lyapunov function and the linear matrix inequality (LMI), the problem of observerbased time delayeddependent passive control is discussed. A numerical example is given to show the validity of the proposed approach.
