Abstract :
This paper proposes a new switching control method of space voltage vector modulation inverter for speed servo system of induction motor. The proposed method shortens the digital control time of space voltage vector modulation inverter and improves the current control performance with wide bandwidth. Moreover, the proposed switching method is implemented by using FPGA in order to enhance its control performance. In addition, by using PI controllers considering voltage saturation, the speed servo system has more stable speed control characteristics. The effectiveness of proposed control method is verified by the experimental results.
