Abstract :
The problem of fuzzy optimal control for nonlinear time-delay system was considered based on the framework of T-S (Takagi-Sugeno) fuzzy model and parallel distributed compensation (PDC) controller. The controller procedure is to solve an optimization problem with linear matrix inequality (LMI) constraints whose feasible solution can be determined by efficient numerical algorithms. An example is given to demonstrate the application of the proposal design methods.
