| Abstract: | This paper describes the schematic of electric propulsion system, then a versatile method based on MATLAB real time simulation tool RTW and versatile data acquisition card PCI-1711 is used to realize the control from load model to simulation converter. The time delay affection to simulation system is simulated by MATLAB/Simulink, and the control preciseness and stability under load model time delay is also analyzed. By building the close loop transfer function of the simulation motor electromagnetic torque control and the drawing frequency field of Bode plot, the time delay is further analyzed, and the close loop gain is modified to compensate the time delay affection. The compensated system control is nearly as good as the unaffected control, and is verified by the simulation results. |
