Description
Summary:The most commonly used controller for the speed control of DC motor drives is PI controller. In spite of the major features of the PI controller, it has some disadvantages such as: the high starting overshoot in speed, the sensitivity to controller gains and the sluggish response due to sudden change in load torque disturbance. Thus, the relatively new integral-proportional IP controller is proposed to solve the disadvantages of the PI controller. Simulation results due to step and impulse response in S-domain and Z-domain are presented for both controllers. Moreover, IP and fuzzy controllers performance are compared. Using computer (80286) as a main controller, these two controllers are compared. Experimental studies are discussed in detail. The experimental results obtained give us good idea about the two controllers, and suggest that IP controller can replace the PI controller for the speed control of DC motor drives.
