FOPID controller is the one of the controllers designed by fractional order concept. This report starts discussion with some basic ideas of PID and fractional calculus and the definitions used in it and literature survey done in fractional calculus, then introduction of FOPID controller and its tuning methods. Any controller has its importance only with some good tuning technique. In this report a classical tuning approach is discussed for tuning in which some specifications are used for obtaining parameters of controller. To use this method modulus, phase and phase slope of process is required. A method to find those parameters also discussed in this report. In PID and FOPID controller Internal Model Control (IMC) approach is the one which got attention now a days. Here introduction of IMC approach, implementation and design of IMC model is presented. Application of this technique on different systems is given and finding controller transfer function in standard form as PID. After that some conclusions are drawn by applying proposed IMC-PID procedure on a first order and second order system with/without time-delay term and also compare the results with Smith Predictor for time-delayed system. Modelling of DC motor as system and controller design through IMC-PID and FIMC approach is given and respective simulations are done from which some conclusions are drawn.
