Abstract

A new fuzzy logic (FL) controller using the TSK technique that will manipulate an AC synchronous motor to produce reactive power to bring the entire system to the optimum operating point is presented. The FL controller performs adequately both rapid and slow changing load condition.The FL controller performance was highly satisfactory in tracking and improving the plant PF to achieve the set point, just like a proportional integral derivative (PID) controller. The FL controller in conjunction with a synchronous motor represents a new practical method to take advantage of facility synchronous motor loads by dynamically monitoring plant eletrical parameters and automatically bringing the over system to the optimum operating point, and could some day be implemented in an industrial plant environment that may require PF improvement with a high degree of accuracy.
