Classical control theory method often cannot obtain good static and dynamic performance in speed control system of asynchronous motor that is multivariable, nonlinear and strong coupling. However, with the application of modern control theory, it can effectively improve the operating performance of system in a complicated environment. This paper introduces the basic principle of vector control system and establishes the simulation model of vector control system of asynchronous motor. Meanwhile, according to fuzzy control theory, this paper shows a design of fuzzy controller and it is applied to the vector control system of speed adjusting module. Finally, it uses Matlab/Simulink to simulate and it verifies that Fuzzy vector control system response faster has better stability and stronger robust performance compared to the traditional vector control.

Considering the characteristics of vector control system, a speed controller based on fuzzy logic is presented in this paper. Using the fuzzy reasoning, we can update the output of the speed controller real time and handle the uncertain information. Results of simulation are provided to demonstrate that the vector control system of asynchronous motor based on fuzzy controller not only has the feature of simple and easy to be implemented, but also has the dynamic performance and robustness.

Vector control technology is regarded as a kind of controlling manner of AC asynchronous motor and it has already become the first method of the high-performance variable-frequency speed regulating system. According to the basic principles of induction motor vector control, this paper constructs simulation model of rotor magnetic field oriented vector control system based on the MATLAB software. The paper analyzes the operation of motor on the basis of mutation of a given speed and sudden load. The simulation result including the oscillogram speed, torque,three phase current and two phase current were presented and analyzed. Results show that it has good dynamic performance, and it realizes the decoupling control system.

Vector Control System

In the AC control system, vector control theory is very popular as it makes the AC motor achieve the performance as perfect as DC motor [1]. In the paper, the vector control theory is briefly introduced, and then a vector control system model is builded in the matlab/simulink, and the SVPWM technique is adopted. The results show that the improved vector control sytem of PMSM has a excellent performance.
