Research on buck converter control based on fractional order PIλDμ controller

For promoting the performance of the Buck converter controlled by traditional PID controller, fractional order PIλDμ controller, which is the generalization of classical integer order PID controller, was proposed. It can be used for fractional order systems and some integer order systems, and may have some superior performances compared with the classical integer order PID controller. Then the genetic algorithm with global searching was used to select optimum parameters of fractional order PID controller based on ITAE performance criteria. The experiment results confirm that the fractional order PI λDμ controller make the controlled system has better static and dynamic properties and robustness under large parameters variation.

Key words:Buck converter,fractional order calculus,PIλDμ controller,parameters tuning
