摘要：Abstract This paper deals with the problem of robust jointly state and fault estimation (actuator and sensor) observer design for discrete-time Descriptor-Linear Parameter Varying (D-LPV) with unmeasurable gain scheduling. The proposed approach is based on the H∞ synthesis applied to the state estimation error. Sufficient conditions are given by a set of Linear Matrix Inequalities (LMIs), which ensures robustness to disturbances/noise and the error given by the unmeasurable gain scheduling functions. Thus, the main contribution is to develop a conceptually simple integrated procedure to estimate states, sensor or actuator faults. In order to illustrate the methodology, simulations based on a realistic model of binary distillation column are considered.
