ADRC WITH SYNTHESIS TUNING ALGORITHM FOR SUPERHEATING STEAM TEMPERATURE OF CFBB
The cascade controller of Active- Disturbance-Rejection-Controller and PI controller is applied to the steam temperature system of circulating fluidized bed, which has the characters of large time-delay, fast time-varying and various disturbances, a synthesis tuning algorithm which combined the intelligent optimal method NSGA_II and numerical optimal method algorithm is adopted to tune the paramcrters of controller. In the computer simulation, all parameters of ADRC and PI controller is tuned with 100％ load. The Least Square algorithm is also applied to tuning PI controller. Then plant with PI controller is looked as a generalized object and fitting function is computed. For the fitting function, multi-objective algorithm NSGA II is applied to tuning ESO. Then NLF is tuned with Non-linear Least Square algorithm -Levenbcrg-Marqudart algorithm. AS the comparison algorithm, PI-PI controller is well tuned with least square algorithm. The simulation with load-varying demonstrated more robustness and the simulation with water-feed disturbance demonstrated more disturbance rejection of ADRC-PI cascade controller.
