Abstract—According to the serious decoupling, uncertainty, easily disturbed and nonlinear characters of the gas mixture of butterfly valve string couplets system, an ADRC static decoupling technology and the dynamic decoupling method based on extended state observer (ESO) were proposed. In this method, coupling from other input, parameters time-varying and external disturbances are all regarded as a total disturbance. The total disturbance can be estimated by ESO and feedback to controller, and coupling is achieved. In order to improve response speed of the system, and reduce the computation, this control system use nonlinear tracking-differentiator(TD), ESO and the nonlinear state error feedback control law (NLSEF) uses nonlinear function.Simulation results shows that, in this method, the decoupling is simplified, and the requirement of the model is reduced. The novel method can also ask for less calculation with faster response and better robustness, still with good tracking performance and disturbance rejection capability, the decoupling effect is fine.

Index Terms—Gas mixing, active disturbance rejection control (ADRC), extended state observer (ESO), decoupling.
