The Application of Fractional Order PI^?D^μ Controller in Coaler

The control to the speed of coaler actually is the control to diesel engine´s speed, in this paper we tune the parameters of fractional order PI^λD^μ controller by using immune clone selection algorithm and simulate the result by using matlab. The result demonstrate that fractional order PI^λD^μ controller has very good dynamic performance and strong robust than general integrate PID controller. It largely improved the defect of speed control system of diesel engine and has broader prospect.
