چکیده
This paper presents the detailed design of Type-2 Fuzzy Logic PI controller to control the speed of a DC servomotor. The controller is explored extensively in terms of number, type of membership functions and judged in 3 different cases; which are unity step response, load disturbance and noise disturbance. The performance of the controller is measured in terms of parameters such as rise time, settling time, percent overshoot and integral absolute error. A comparative analysis with the conventional type-1fuzzy logic PI controller shows that overall, type-2 showed much improved results. This improvement is evident when it comes to handling of load disturbance and noise added to the system.
