microcontroller based speed control of separately excited dc motor

Abstract

A PIC microcontroller based closed loop speed control scheme has been developed for the speed control of a separately excited DC motor fed from PV array. An IGBT based boost converter is used as an interface between PV array and the DC motor. The microcontroller has been programmed to automatically vary the duty cycle of the boost converter depending upon the set/required speed of the motor. The DC motor model has been developed and the complete simulink model of the proposed scheme has been built using MATLAB/PSB. Simulation studies and experimental investigations have been carried out on a laboratory size prototype separately excited DC motor fed from a PV array and the results are presented. The comparison of experimental and simulation results shows very close agreement between the two thus validating the controller proposed.

wish to make a small project on the topic. studying power electronics in t.e. engg.
please guide with whatever you can.
topic alloted was microcontoller speed control using semiconvertor of separately exited dc motor.
total amatuer here. rectify and help , also suggest alternate project in power elec if this not suitable.
