Design and Implementation of Fractional Order PID Controller for Integer and Fractional Order Thermal Process

Recently, The fractional order PID control is the generalization of the PID control, has been focused. For implementation of FOPID, approximation of the fractional integrator and differentiator is required. Short memory principle (SMP) is one of the effective approximation methods. However, there is a disadvantage that the approximated filter by the SMP can’t eliminate the steady state error. To overcome this, we introduce the distributed implementation of integrator technique. Fractional order PID control for Integer order and fractional order thermal process is proposed and implemented in MATLAB and compare it with traditional PID control scheme.
