Research Title
Fault Diagnosis and Fault-Tolerant Control of Chemical Process Systems

Research Objectives
This research aims at developing a fault diagnosis and fault-tolerant control framework to handle equipment abnormalities in chemical process systems. One goal of this work is to identify faulty actuators or sensors in a process control system. In particular, we explore how to utilize the information embodied in a process model to identify the faulty equipment. The other goal of this work is to handle severe actuator faults that preclude the possibility of continued operation at the normal operating point. For this problem, we investigate how to utilize the remaining control action to achieve stable operation during the period of fault rectification. Specifically, we address several issues for the practical implementation of the “safe-parking” approach (a fault-handling methodology to maintain a process at an appropriate temporary operating point), such as changes in process dynamics, actuator frozen at an arbitrary position, and the network structure of a chemical plant. The results of this work are expected to help people enhance profitability and safety of chemical process operations.
