Model identification of coupled-tank system — MIMO process

Model identification of a linear system is a matured topic in control engineering. Whereas identifying the model of a nonlinear multi-input-multi-output (MIMO) system is more challenging and complex task. In chemical industries, coupled-tank system is a very well known process entity which is also MIMO in nature with nonlinear behavior. Here, in our reported work, we have identified the model of a laboratory scale coupled-tank system based on physical laws and the identified model has been validated through real-time experimentation.
