Modeling and Control of Electric Drive for an EV
摘要
Electric vehicles (EVs) have a huge amount of potential in the future. An EV motor drive system is the most essential power conversion equipment. The research is strategically positioned at the intersection of electric drive technology, environmental consciousness, and the imperative to integrate renewable energy sources. For propulsion, electric vehicles need AC or DC electric motors, rechargeable batteries, and controllers. The power move through the powertrain during motor and recovery conditions is calculated and their comparison is conducted relative to typical driving cycles, and the results are graphically shown. A three-phase inverter is specifically designed to provide power and control for a brushless DC (BLDC) motor. The effects of torque, motor speed, and regenerative braking on the performance of the battery and the energy requirements for normal driving cycles are estimated and displayed. In addition, a model of electric drive-controlled BLDC motor and vehicle dynamics is developed to verify the system by using MATLAB.
