Abstract

A Model Predictive Control (MPC) based fault tolerant control application has been described. The controller was applied to control the concentration and level of a solid crystal dissolution tank. The system was frequently suffering process upset due to difficulty in solid discharge. The controller used an error calculated from an intermittent signal as a feedforward to the controller. The intermittent signal posed challenges in model development and also for control. An iterative technique was used to develop the model. The developed controller successfully eliminated the operational problem.
