Design and simulation of fuzzy controller based (IPM) converter fed DC Motors

This paper proposes a DSPF2812 based 32-bit micro-controller is used to to generate PWM waveform required to switch IPM DRIVE, by using fuzzy logic controller to control dc motor fed by AC/DC (IPM) converter. 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 consists of an inner ON/OFF current controller and an outer fuzzy speed controller. The fuzzy speed controller is used to change the duty cycle of the(IPM) 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. Simulations results are presented to demonstrate the proposed performance and then, compared with the reported results and found that the performance of fuzzy based IPM DRIVE drive for DC motors is improved.
