Optimization of the Stator Current Vector Control System of the Electric Vehicle Drive with Induction Motor

A method for the synthesis of a speed control system with optimized vector control of the stator current of an induction motor of an electric vehicle has been developed. This provides the maximum value of the electromagnetic torque at the same value of the current in the stator winding. The comparative analysis of traction properties of the induction motor at application of the optimized and not optimized vector control of stator current is carried out. The formula is obtained, which allows at the same value of current in the stator winding of the induction motor to determine the multiplicity of increase of electromagnetic torque using optimized and non-optimized vector control of the stator current of the induction motor of an electric vehicle.
