Generalized Extended State Observer based Speed Control for DC Motor Servo System
【摘要】:This paper presents a speed control method for a DC motor servo system(DCMSS) based on a generalized extended state observer(GESO).First,the model of the DCMSS and a preliminary-standard ESO based control method are described.Next,a GESO based control method is proposed for the non-integral-chain DCMSS to estimate and compensate the lumped disturbance in real time.By appropriately choosing a disturbance compensation gain,the effects of the parameter variations and the load disturbance are removed from the output channel of the system.Then,a stability criterion and a design algorithm for the GESO-based DCMSS have been developed.Finally,simulation results demonstrate the validity of the method.
