摘要：AbstractA general electric vehicle (EV) consists of many subsystems such as battery, bidirectional boost/buck converter, inverter, motor, and vehicle body. The bidirectional converter is used for flexibility in the choice of battery voltage and input voltage of inverter. Due to the different speed profiles i.e., idling, acceleration, deceleration, and steady state within a drive cycle, the transition from one to another may cause high switching spikes in battery current, dc-link voltage, and motor torque using conventional single loop speed controller. These spikes have detrimental effect on the performance of EV such as battery life, component failure, switching loss, and vibration. To reduce the spikes in the power stage and to enhance the dynamic response while tracking the drive cycle, a reset switch (RS) and bias have been proposed in this paper. As this technique is implemented in control circuit therefore it is cost-effective and simple. Small-signal transfer function analysis has been done to select the gains of the proportional-integral controllers as well as to check the stability of the overall system. To validate the proposed technique, a switched nonlinear dynamic model with non-idealities of the permanent magnet brushless dc (PMBLDC) motor driven two wheeler (2W) vehicle is designed and tested using Indian Drive Cycle (IDC). Improvement of different performance indices of EV including the increment in the range on single charge has been observed for the proposed technique.
