Research on Sensorless DTC System of Induction Motor
Introduces a method of no speed sensors DTC system of asynchronous dynamo based on MARS theory and researches on its control strategy.In order to improve the accuracy of the stator flux linkage observing,introducing the stator flux linkage observing model combining the advantages of a conventional voltage and current model instead of conventional voltage model to observe the flux linkage.Aim at motor performance problems caused by flux linkage observation error in controlling,for the pure integral term of in traditional flux linkage observer improved,applicating low-pass filter to compensate stator flux,so it has simple structure,convenient realize and exact flux linkage observing.In this paper,on the basis of establishing the control model,with TMS320LF2407A as master control chip,using IPM as the main circuit inverter,setting up the experimental system and doing experiment,the experimental results proved the validity of the model and the feasibility of the design of the system.
