摘要：
For the multi-inputs and multi-outputs strong coupling coordinated system of once-through boiler unit, the active disturbance rejection controller of coordinated system is designed based on pseudo diagonalization. Inverse Nyquist array is employed to carry out frequency domain analysis of the model. Pseudo diagonalization is used to design the static decoupling compensation matrix of the system. The dynamic coupling and system unknown parts are observed by extended state observer of ADRC and is compensated to the system. The simulation tests show that, the disturbance rejection results of the load and the main steam pressure for the coordinated control system under LADRC are better than that of PID control.
