Fault detection and isolation in a greenhouse using parity relations

摘要

The paper presents the application of parity relations method to fault detection and isolation (FDI) in a greenhouse process. The considered faults include greenhouse sensor and actuator faults. The diagnosis method is applied in simulation to a non-linear process describing the greenhouse. Therefore, a linear model is first identified. Based on the identified model a linear residual generator is then designed using parity relations.
