The mathematical model of the modem induction traction motor (TRIM and cutting magnetic circuit traction motor), supplied with IPM inverter with different control technique is presented in the paper. In electric and hybrid vehicle are applied: FLMC (Fuzzy Logic Mode Control), SLMC (Sliding Mode Control), NRMC (Neural Regulator Control), and Direct Power and Torque Control for Space Vector Modulated inverter (DPTC SVM). In the special solution of the electric and hybrid vehicle are also applied a Random Switching Frequency Modulation. The control of hybrid vehicle should assure the realization of established transport-assignments in the definite time, at the optimum of energy consumption. One can this realize using. The multi criteria control system. Some results of the computer simulations are presented in the paper. Results of numerical calculation were verified for laboratory model of the electric and hybrid wheel vehicles traction motor. 展开更多
