Due to adding the extra degree of freedom, the fractional order PID controllers can achieve better control performance than the integer order PID controllers. The present paper proposes a novel fractional order controller design method, inspired by the Kessler's optimum magnitude method. The explicit tuning rules are accessible even to less experienced users in fractional calculus, taking only the advantages of the controller and not the disadvantage of complex mathematical background. The advantages of the method are demonstrated by a case study.
