Fault Diagnosis Strategies for Batch Reactors

In chemical processes, several kinds of failures may compromise safety and productivity. Indeed, the occurrence of faults may affect efficiency of the process (e.g., lower product quality) or, in the worst scenarios, could lead to fatal accidents (e.g., temperature runaway) with injuries to personnel, environmental pollution, equipments damage. [Pg.122]

The term fault is generally defined as a departure of an observed variable or a parameter from an acceptable range [19, 48], The causes of this abnormality, such as a failed coolant pump or a failed sensor, are called basic events or root events and are often referred as malfunctions or failures. [Pg.122]

Fault Diagnosis (FD) consists of three main tasks  [Pg.122]

Once a fault has been detected, in some applications a controller reconfiguration for the self-correction of the fault is required (fault accommodation). A fault-tolerant control system possesses this capability, and its adoption is of the utmost [Pg.122]

The relative importance of the three above-mentioned diagnosis tasks depends on the application at hand. However, while fault detection is an absolute must for any practical system, fault identification, even if helpful, is not essential when controller reconfiguration is not required. [Pg.123]
