Abstract :
This paper considers a nonlinear optimal control of fuzzy systems with input constraint and decay rate. The fuzzy system considered in this paper is the Takagi-Sugeno fuzzy system. The optimal controller for Takagi-Sugeno fuzzy systems is designed by following a simple controller synthesis procedure, which is essentially given as the semidefinite programming problem. The usefulness of the proposed approach is illustrated by considering the three-axis attitude stabilization problem of rigid spacecraft.
