A novel Green Plug Filter Compensation scheme for electric vehicle DC drive

摘要

The paper presents a new Green Plug Filter Compensator and coordinated control strategy for Battery Powered Electric Vehicle. The integrated drive scheme is fully stabilized using a novel FACTS based green filter compensator developed by the Second Author that ensures stabilized DC bus voltage, minimal inrush current conditions and load excursions when load demand exceeds the Nickel-Metal-Hydrid cell battery capacity. The paper presents a Modified Tri-loop PID controller to control the DC/DC converter, Green Plug Filter Compensator GPFC scheme using dynamic error tracking. This paper presents also the dual regulation Modified PID Tri-loop controller for a Nickel-Metal-Hydrid cell battery powered four-wheel drive electric vehicle. A Tri-Loop dynamic error driven control scheme is proposed to regulate the DC motor current, limit inrush current and power speed overloading conditions, in addition to motor dynamic speed reference tracking. A type B Dual DC/DC converter is employed to match and control the power transfer from the Nickel-Metal-Hydrid cell battery to the PMDC motors load. All Matlab Digital Simulation Functional Models for the Fuel cell, DC/DC converter, PMDC motor, interface LC-Filters, and Controller Loops are fully modelled using Matlab/Simulink/Sim-Power Software Environment.
