| Abstract: | A new fault detection method for a class of linear systems with general failure and GPC(Generalized predictive control)-based fault tolerant control are studied,and a GPC fault tolerant control law is proposed.A fault observer is designed to detect failure and disturbance,and then these estimated information is used to predict the model output in order to obtain the fault tolerant control law.Simulation example shows the effectiveness of the fault detection scheme and the GPC fault tolerant control law. |
