Fault-tolerant control of nonlinear process systems: Handling sensor malfunctions

Increasingly faced with the requirements of safety, reliability, and profitability, chemical process operations are necessarily relying on highly automated control systems involving a large number of sensors. As process devices, sensors are subject to failure, intermittent sensor data losses, biased measurements, etc., but as information sources sensor failures lead to erroneous control system actions, potentially causing a host of economic, …
