| Abstract: | Considering the nonlinearity and time-variant,large time constant and dead time in water supply process,a data-driven method virtual reference feedback tuning（VRFT） was introduced to the IMC-PID tuning,and a novel VRFT-IMC tuning method without using model parameters was presented.This method combines strong robust in IMC and model-free adaptive in data-driven control.Simulation results show that IMC-PID method based on VRFT outperforms the traditional IMC-PID,and can be used for initial tuning of the controller and auto-tuning in the turbidity control. |
