Abstract


Designing of controllers for control of various motors has been an exciting field for the researchers. Talking of controllers, PID controllers are the most popular among the various industries. Nowadays Fuzzy Logic Controllers (FLC) and PID like FLCs are very famous due to its robust design, faster response and accuracy. In this paper we have proposed a novel method to control a stepper motor with PD like FLC that can handle one sided errors like those in tracking problem such as tracking the Sun and maximum power point in PV array system. During simulation it is seen that the controller can easily handle different errors without much of oscillations. The speed of response mainly depends on the step size of the stepper motor.

Keywords: Tracking problem, PD like Fuzzy Logic Controller, Stepper motor control. Matlab/Simulink, Fuzzy Logic toolbox.
