Modern Control Techniques Used in Hybrid Drive Systems

The mathematical model of special construction induction motor, supplied with IPM inverter, with different control technique is presented in the paper. Induction motor drives system applied in modern hybrid vehicle, insensitive to parameter and operating condition changes, can be achieved using modern control techniques. In wheel vehicle drive system are applied: Fuzzy Logic Mode Control (FLMC), Sliding Mode Control (SLMC), 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. Some result 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.
