چکیده:

This paper applies the Pulse Width Modulation to indirect Field Oriented Control of an induction machine in parallel Hybrid Electrical Vehicle to enhance the performance and the stability of the system.To control the rotor speed of the induction machine, a PI controller is employed. A hysteresis current controller is applied for controlling the output voltage of the PWM inverter which is fed the induction machine.To justify the correctness of the system and its feasibility, the simulation method is selected. The model of the system is implemented in MATLAB Simulink software, which is suitable for testing the dynamic simulation of a system. By this simulation, the various working conditions of an induction machine are studied.In conclusion, this paper shows that the indirect field oriented control is a good approach for controlling the induction machine. As a result, the induction machine responses to torque changes very quickly and precisely. However, the simulation result in various rotor speeds shows that the machine responses reach their steady state condition slower than the various torque conditions. Nevertheless, this paper is the control of the induction machine in a parallel Hybrid Electrical Vehicle which only has a torque coupling.
