Abstract :
The paper presents the design and comparison of type-1 and interval type-2 fuzzy logic controllers for ball and beam system. Both the controllers utilize the beam angle as a scheduling variable for the stabilization and tracking of the ball position. The performance of the controllers is analyzed by simulating them in MATLAB environment for various initial conditions and in the presence of disturbance signals. It is shown that interval type-2 fuzzy gain scheduling controller has a better response and disturbance rejection capability as compared to type-1 fuzzy and conventional pole placement controller.
