This paper presents a new energy and power management control strategy for battery electric vehicle (BEV) with supercapacitors (SCs) based on speed command and acceleration estimation. The purpose of the control strategy is to increase the capability of regenerative braking energy capturing and to improve DC bus voltage regulation. The control strategy uses cascade voltage and current control of SCs...
A sensorless extended Kalman filter (EKF) based direct torque control (DTC) with the use of a constant switching frequency control (CSFC) of induction machine is proposed in this research work. This paper is meant to investigate the dynamic performance for DTC-CSFC and DTC with a hysteresis torque controller by applying different speed step changes from three different low speed operations. The dynamic...
This paper proposes a new control strategy and design for auxiliary power source using in Battery Hybrid Electric Vehicle (BHEV) based on acceleration power. The control strategy takes actual speed, acceleration and terminal voltage of supercapacitors (SCs) into account for controlling the energy and power demanded. The detail design of the auxiliary power source and its dynamic control are demonstrated...
This paper presents the control system of energy management for electric vehicle (EV) applications, based on the actual speed of the vehicle and the terminal voltage of supercapacitors (SCs). The cascade control of voltage and current were implemented on SCs for tracking the energy during acceleration and braking. The performances of SCs concerning the dynamic power were examined. A reliable power...
