Simulation of Vector Controlled Adjustable Speed System of Doubly Fed Induction Machine

Abstract

In this work the performance of vector speed control of doubly fed induction machine is considered. Based on the analysis of doubly fed induction machine dynamic mathematical model and the vector control principle, the construction of the motor control system has been completed. Doubly fed induction machine module, the vector controller module, Clark transform module, Park transform module, inverter module, flux module, speed-conditioning module have been set up by0adopting the idea of modular in MATLAB/SIMULINK environment. Through the organic integration of functional modules, the vector control doubly fed induction machine system has been constituted. Simulation results show the changes in the machine electromagnetic torque, the dynamic changes of speed curve, which demonstrate that the real system can be well simulated with fast dynamic response speed, steady-state small of static error, and strong ability of anti-load disturbance.
