Power system fuzzy bang-bang stabilizer design VIA critical path method

This paper addresses a new approach, called the optimal path estimation method (OPEM), to implement the time optimal bang-bang control. The method is based on feedback information obtained by estimating the distance from the present state to the switching surface along the optimal trajectory. A fuzzy algorithm is used for the implementation of the control logic. Advantages of the proposed method over traditional bang-bang control method are illustrated by numerical simulations of a multimachine infinite-bus power system
