| Summary: | This paper addresses the design, simulation, commissioning and testing of an electrodynamometer (ED) to assess the dynamic performance of Electric Vehicles (EV). The EV-ED system is comprised of two electric machines coupled mechanically. The traction machine is a 7.75 kW Permanent Magnet Synchronous Motor which is controlled by means of a vector control and it is coupled mechanically to a similar machine which is used as a mechanical load. The load machine was fed by two DC/AC converters connected by the DC bus allowing bidirectional power flow. The electrodynamometer was controlled by means of a Nati onal Instruments electronic board and Labview software. Several load profiles and inertias were programmed to emul ate an Electric Vehicle (EV). The traction machine drive was implemented with a PP75T120 Powerex Inverter. PWM generation and control strate gy were implemented on a MC56F8357 Freescale Digital Signal Controller (DSC). The speed control of the traction machine was validated for different driving cycles. Matlab/Simulink simulations of the machine control and electrodynamometer along with experimental results illustrating the resp onse of the machine control under the c haracteristic load profile of an EV are presented and analyzed. Traction and regenerative breaking stages are analyzed and discussed broadly. |
