Robust Flux Observe Method for Stator Resistance of Long Cable Driven High Power Induction Motor
摘要
Abstract
In the long cable driven induction motor drive systems,speed sensorless control is usually adopted due to the long distance between the controller and the motor.In addition,long cable increases the stator side impedance of the induction motor,especially the equivalent stator resistance by an order of magnitude,which increases the impact of the temperature drift of the stator resistance on the flux observation and reduces the performance of the flux observer.A magnetic flux observation method with strong stator resistance robustness was proposed for induction motor drive systems powered by long cables..This method improves the traditional hybrid model flux observer,a model reference adaptive speed observer that is completely robust to the stator resistance was used to obtain the speed,meanwhil,the current model was used to calculate the rotor flux,and this flux calculation process was used to replace the original current model.The flux calculation process is completely robust to the stator resistance,so the robustness of the observer to the stator resistance is improved.Hardware-in-the-loop(HIL)test results verify the feasibility and effectiveness of this method.关键词
