Abstract:
This paper discusses the system identification of Multi-input Multi-output (MIMO) system and design of Model Predictive Controller (MPC) for identified model. Distillation column process is taken for studies. It is an important processing unit in petroleum refining and chemical industries, and needs to be controlled close to the optimum operating conditions because of economic incentives. Subspace identification method is used to identify the MIMO model and Model Predictive Controller is designed for identified model. MPC is widely adopted in the process industry as an effective means to deal with large multivariable constrained control problems.
