Abstract:

By using the LMI method，the problem of H∞ guaranteed cost fault tolerant controller designs for TS fuzzy system is studied.  The fuzzy timedelay systems with admissible uncertain parameters and actuator failures are dealt with, and the least upper bound of the guaranteed cost function and H∞ performance are considered simultaneously, the sufficient condition for the existence of the H∞ guaranteed cost fault tolerant controller for TS fuzzy systems is given in term of LMIs. The problem on designing a controller is transformed into a linear matrix inequality (LMI) feasibility problem．The simulation example shows the feasibility and effectiveness of the design procedures.
