Research project

Title: Model based fault-tolerant control of process systems

The operation of process plants to continuously meet their performance target is becoming even more challenging. Worldwide competition, the requirement for cost-effectiveness and safety regulations are the main reasons for tight product quality specifications. Nonlinearity, uncertainty and the occurrence of faults make the problem even more complicated to tackle.

Model predictive control (MPC) is an advanced control technique with an optimization based control strategy. MPC uses an explicit model to predict the future behaviour of the plant and solves a constrained optimization problem on-line to obtain the optimal control sequence.

The main objective of this work is to design fault tolerant nonlinear model predictive controllers for process systems. The proposed method is based on how fault is diagnosed and fault-tolerant design method can be incorporated in an MPC framework.
