In this paper, a two-phase hybrid particle swarm optimization (PSO) approach is used to solve optimal reactive power dispatch (ORPD) problem. In this hybrid approach, PSO is used to explore the optimal region and direct search is used as local optimization technique for finer convergence. The performance of the proposed hybrid approach is demonstrated with(More)
The Knowledge Base of a Fuzzy Logic Controller (FLC) encapsulates expert knowledge and consists of the Data Base (membership functions) and Rule-Base of the controller. Optimization of these Knowledge Base components is critical to the performance of the controller and has traditionally been achieved through a process of trial and error. Such an approach is(More)
Conventional PID controllers have been widely applied in industrial process control for about half a century because of their simple structure and convenience of implementation. The implementation of PID controllers needs proper tuning of proportional gains, integral gains, and derivative gains of the controllers. Among the existing gain tuning techniques,(More)
