Conference paper
Part of the Advances in Intelligent Systems and Computing book series (AISC, volume 213)

Abstract

Though fractional calculus has been used in control theory for several years, it has been applied to rotation speed control of hydraulic turbine little. In order to improve transition of hydraulic turbine under load disturbance, application of fractional order PID (FOPID) controller to hydraulic turbine governor based on nonlinear model is presented and studied. And optimal parameters are found with particle swarm optimization (PSO) algorithm. Comparisons are made with a PID governor. Simulation results show that fractional order PID controller provided better dynamics than classical PID controller, and fractional order control theory is an effective method for hydraulic turbine governor.
