The main aim of this study was to control the nonlinear process using multi-model PI controller. A multi model is developed for conical tank and it is validated against the real time setup conical tank process. A Multi model based PI controller is also developed, and implemented with real-time setup, and their performances are compared with that of the conventional controller of real time setup. The multimodal philosophy is based on the selection of a set of linear models, and the weighted sum of output from the multimodal N-PI has been used to control the nonlinear conical tank process.
