Active Disturbance Rejection Decoupling Control Method for Gas Mixing Butterfly Valve Group

摘要

This paper proposed an active disturbance rejection control (ADRC)method for gas mixing butterfly valve group. According to the serious decoupling, uncertainty, many disturbances and nonlinear etc of the gas mixing butterfly valve group, the model of the plant is established, proposed the ADRC based on static decoupling and ESO dynamic decoupling in order to eliminate the coupling between the loops. Simulation results show that the designed controller not only has good decoupling pedormance, but also ensures good robustness and adaptability under modeling uncertainty and external disturbance.
