Abstract

A fuzzy controller for various types of DC motor fed by DC/DC converter is designed and presented in this paper. The fuzzy controller is designed in such a way that it can be implemented in a micro-controller or DSP processor based embedded system. The system designed has two loops with an inner ON/OFF current controller and an outer fuzzy speed controller. The later is used to change the duty cycle of the converter and thereby, the voltage fed to the DC motor regulates its speed. The performance in respect of load variation and speed change has been reported. The performance of the proposed controller is compared with the reported results and found that the fuzzy based DC-DC drive can have better control.
