Abstract :
This paper presents a novel nonlinear parity equation residual generation scheme for fault detection and isolation. The scheme is applied to the problem of health monitoring of an automobile internal combustion engine during execution of a standard US Environmental Protection Agency inspection and maintenance test cycle. The fault detection and isolation scheme is shown to be sensitive to actuator and sensor faults and the scheme is robust to the unmeasured load torque acting on the engine.
