Abstract

This paper will establish the simulation model and the inverter model of induction motor based on the multi function simulation software AMESim. Considering the influence on the motor from the temperature and other complex factors, and Using Matlab / Simulink software to establish a simulation model of direct torque control system, then we go on combined simulation through the combination of the two aspects. The simulation result shows that the controller make the speed faster and the robustness stronger of the motor control system, but at the same time it exposes the shortcoming that torque pulsing will enlarge at the low speed. Pointing at the shortcoming, this article starts with the principle of extended kalman filtering algorithm, uses of measuring current, voltage on the pattern of stator, deduces from a new motor speed, flux state observer model without speed sensor, and estimates the rotor speed and stator flux. The simulation result shows that this method can solve the problem of flux and torque pulsing effectively.
