Conical tank system is a non-linear system. Due to its non-linear behaviour, it is a challenging problem to control the liquid level in the tank. Real time processes are always exhibits non-linear property. In many process industries like Chemical industries, Petroleum industries, Paper industries, Water treatment plants, Fermentation industries etc.., it is preferred to have conical tank system because, it leads to better drainage of solid mixtures, slurries and viscous liquid at the bottom of the tank. In this project work, Internal Model Controller(IMC) is designed and response of the process is obtained in both simulation and real time. Due to changes in process parameters the behaviour of the system can be varied. To measure an exact performance of the system, the faults introduced into the conical tank system and to be detected. If not, the faults which degrade the performance of the system. Various fault diagnosis methods are to be considered. PID controllers are used to detect the faults in conical tank system. Consequently, they can provide better output performance which can be measured in terms of overshoot, set point tracking and settling time.
