An Experimental Research on Vector Control of Induction Motor Based on Simple Model

Given the heavy computation, easy saturation and cumulate errors of conventional direct vector control, the vector control of induction motor based on simple model is studied and the detailed scheme is described on the basis of the decomposing and approximating the rotor flux. Because of the direct closed-loop control of the magnetizing current and the torque current and the complex current regulator is completed by PI regulator, so the direct vector control of induction motor is simplified. The experimental results show that the proposed method is effective in decreasing the dynamic disturbance and has the advantages of the simplicity of the code program, rare saturation and shocks.
