摘要：This paper proposes an H−/H∞ fault detection observer method by using generalized output for a class of polytopic linear
parameter-varying (LPV) systems. As the main contribution, with the aid of the relative degree of output, a new output
vector is generated by gathering the original output and its time derivative, and it is feasible to consider H− actuator fault
sensitivity in the entire frequency for the new system. In order to improve actuator and sensor fault sensitivity as well as
guarantee robustness against disturbances, simultaneously, an H−/H∞ fault detection observer is designed for the new
LPV polytopic system. Besides, the design conditions of the proposed observer are transformed into an optimization problem
by solving a set of linear matrix inequalities (LMIs). Numerical simulations are provided to illustrate the effectiveness
of the proposed method.
