英文摘要 | This paper is devoted to the design of the nonlinear output feedback controller for an industrial evaporation system using input-output linearization technique. The nonlinear output feedback controller consists of an input-output linearizing and decoupling controller, single-input single-output controllers and reduced-order observer. The performance of the nonlinear output feedback controller is verified through closed-loop simulation studies all the evaporator model. Simulation results indicate that the nonlinear controller provides superior unmeasured disturbance rejection capability than the existing multi-loop PI control scheme, and deliver good stabilization properties on the evaporator in the presence of significant model uncertainties. On-site implementation procedures for the nonlinear output feedback controller on the industrial evaporator are discussed. |
