Micro-electric Vehicle Drive Control System

To reduce energy consumption and decrease the hazardous tail pipe emission, significant efforts have been accumulated globally to push the Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) program into mass-production stages. Consequently, it is expected that the internal combustion engine powered vehicles will eventually be replaced by electric ones.The thesis is focused on the study of the permanent magnet brushless DC motor (BLDCM) drive with application to Electrical Vehicles. The main work is the design of a high performance control system based on a TMS320LF2407 DSP.Firstly, based on the comprehensive review of the characteristics and control methods of BLDCM, the operating states and control strategies of a BLDCM with applications in EV are proposed with respect to Power electronics, Electronic technology, Micro Electric technology, special integrated chips and the theory of Motor control theory.The velocity closed-loop control system for a BLDCM based on DSP TMS320F2407 is then designed. Thirdly, the performances of the control system are numerically studied by using Simulink. Finally, the designed control system is experimentally investigated on a prototype motor. Both numerical and experiment results show good agreements with each other, which positively confirms the feasibility and practicability of the proposed control system.
