Indirect DC advanced vector control based on anti-saturation block and voltage limitation

摘要

This paper investigates an indirect DC vector control based on anti-saturation current controller and voltage limitation considering to voltage limitation. We investigate a novel method based on anti-saturation block that combined with the advanced vector control to improve problems of the PMSM (Permanent magnet synchronous machine) control methods. Also it is used to avoid saturation of the stator current and the inverter voltage controller that don't allow these controllers to going to saturation at high speeds. And it can eliminate the error between the input and the output. Generating the references voltages from the obtained references current causes the lack of proper coupling between the d-axis and q-axis. Control in a wide range of speed, increase the speed due to use the voltage limitation, no need to the high speed estimator opposite of the direct vector controller, avoid saturation of the controllers and reduce costs by remove the estimator and control the current ripple in appropriate value are advantages of the indirect vector control, also this method makes independent and proper control of the flux and torque. To assess and confirm the performance of the proposed system, the system is simulated by MATLAB / SIMULINK.
