Abstract : Various non-linear systems are well designed using a non-integer order mathematical model based differential and integral components. The fractional-order concept provides an effective method for turning the technology robust in various industry applications. This paper presents a fractional proportional-integral-derivative (FPID) controller and its benefits in variable speed wind turbine (WT) application. The FPID controller improves the operational environment of WT from the initiation of two more tuning parameters i.e., the fractional-order integral and derivative gains. These gains are well-tuned using the manual tuning method. For analysis of the effectiveness of the FPID controller, a comparison has been carried out between FPID and conventional PID controllers. The overshoot, rise time and settling time in various parameter responses like rotor speed, electromagnetic torque, and load power are considered for comparison of effectiveness of both the controllers. Performance indexes are also calculated and compared for both the controllers.
