Applications Of Auto Disturbance Rejection Control Technology In MIMO Control System

The paper mainly studies ADRC's applications in MIMO control systems.The paper studies the forming process of ADRC and analyzes the make up of ADRC. The discrete formula of ADRC is also provided. To get the parameters'value of ESO, a method based on simplex algorithm is put forward, and the common process to get the parameters'value of ADRC is also given based on a lot of simulations. The paper studies the appropriate objects that ADRC applies in, and extends the technology of ADRC to get model compensation ADRC and ADRC with the form in series.In the paper, ADRC technology is applied in three representative control systems- the ball tube mill system,the coordinated control system of a power unit and the Circulating Fluidized Bed Boiler Combustion Process. The corresponding control scheme is put forward, and the simulation results prove that ADRC has a good control performance in decoupling and anti-disturbances.
