A New Approach for Loss Minimization Control of Induction Motor Drive for Electric Vehicle
In the traditional loss minimization control system of induction motor drive for electric vehicle, the improvement of the efficiency is at the cost of deterioration of the dynamic response. Inspired by the ideas of voltage space vector and direct torque control, a new strategy of directly selecting the voltage vector is pro- posed in this paper, which realizes high behavior con- trol in dynamic processes of load variety. Different from both the direct torque control and the classical vector control, this scheme combines vector controls good stable performance and direct torque controls fast dynamical response, whilst it does not increase any hardware in the control system. Simulation results show that, this scheme, which has excellent dynamic performance, notably reduces the speed-fall of loss minimization control system in dynamic processes. It is an efficient solution to the contradiction between the loss minimization and fast response control.
