PROJECT TITLE :

Emulating On-Road Operating Conditions for Electric-Drive Propulsion Systems

ABSTRACT:

This paper provides a replacement approach for emulating road load conditions for an electric-drive vehicle (EDV) system on a take a look at bench setup consisting of a drive motor (DM) connected to a dynamometer. Two totally different ways of EDV emulation are discussed, that are primarily based on a predefined drive cycle and unpredictable driving behavior. The impact of total vehicle inertia is considered for both situations, and a control scheme is developed for every case primarily based on vehicle equivalent rotational inertia. This technique of EDV emulation not only takes into consideration all of the stress imposed on the DM due to vehicle inertia result, however conjointly permits electric vehicle emulation for any customary drive cycle, along with undefined driving situations. Simulations are conducted for every case employing a MATLAB/Simulink take a look at bench model, and therefore the results are validated using ADVISOR, a well-proven software package, to verify the effectiveness of the proposed methodology. To investigate hardware-in-the-loop real-time performance, each methodology is applied to the experimental test platform, and the accuracy of the experimental results is compared to the results obtained from simulation.
