Real-time implementation of multi-loop internal model controller for two interacting conical tank process

The design and implementation of proposed multiloop internal model controller for two interacting conical tank process (TICT) is described in this paper. The step response based model is designed and it is approximated into first order plus dead time (FOPDT) system. The control loop interaction and pairing analysed by Relative Gain Array (RGA) and Niderlinski index(NI). The multiloop internal model based controller (IMC) is designed for TICT process. The Controller is implemented and experimental results are presented.
