R&D of Trial Instrumentation for Electric Propulsion Motor Drives

Study presents the basic components of the electric propulsion motor drive technologies. Attention is paid to the study of HEV/EV topologies, electric motors, power electronic devices, energy storage applications for the propulsion drive systems as well as regenerative braking and charging systems. Manuscript consists of three models: the load model of the propulsion drive, the computer model of the propulsion drive system and experimental setup. All the models are scaled to the real vehicle. Moreover, the requirements related to control restrictions and tuning possibilities of the EV/HEV propulsion drives. The goal is to propose a methodology for adjusting the electric drives under the test cycles different from the standard testing cycles. By estimating the drive responses, the discussed methodology helps to measure the steady-state and transient vehicle quality and to recommend approaches to the drive regulator tuning, control looping, sensor allocation, and feedback arrangements.
