Active Disturbance Rejection Control of Drum Water Level with Generalized Extended State Observer
Time-varying disturbance of drum water level is difficult to estimate and compensate,which leads to time-varying periodic error of the whole system.System model is reconstructed by using prior information of equivalent disturbance,and the components of known modes in equivalent disturbance are estimated and compensated by the generalized extended state observer.Thus,the error can be eliminated and the control accuracy of the system can be improved.Compared with the traditional active disturbance rejection control(ADRC)system based on linear extended state observer,the control performance under different types of external disturbances is studied.Simulation results show that the proposed generalized extended state observer can completely estimate and compensate the components of the known modes in the equivalent disturbance with small overshoot,short adjustment time,strong anti-interference ability and high control precision.
