Modeling and Simulation for AC Adjustment Speed System of SVPWM Control

摘要

Used Space vector, a new method of alternating machine speed adjustment is discussed. Both single neuron proportional-integral speed controller and torque compensator are introduced to the scheme. Simulation results demonstrate that the proposed control scheme can obtain a robust fast speed control. The system is not sensitive to motor parameters. Simulation is carried out to find out the factors which may affect harmonic distortion of the inverter and we obtain several valuable conclusions.
