The design of multimodel controller for nonlinear process is done with the model bank determination on the basis of Gap metric. Multi linear model controller is designed based on the local linear models by using direct synthesis method with PID filters. Final controller for non-linear model is designed by implementing fuzzy algorithm for all the local linear controllers. Using the direct synthesis method, a proportional-integral-derivative (PID) controller in series with a lead- lag filter is designed for control of the open-loop linear stable and unstable processes. Set-point weighting is considered for reducing the overshoot. The proposed scheme consists of only one tuning parameter and guidelines are provided for selecting the tuning parameter. Good nominal and robust control performances are achieved with the proposed method.
