This paper deals with the fault detection occurred in the mechanical position sensor of a mechatronic actuator Pierburg which is used in the BMW M57 diesel engine. This actuator is in charge of the control of the input air in the vehicle engine. Concretely, it is located between the throttle valve and the combustion chamber. It is supposed to ensure the control of air flow entering to the cylinder...
The work treats the problem of fault detection for processes described by partial differential equations as that of maximizing the power of a parametric hypothesis test which checks whether or not system parameters have nominal values. A simple node activation strategy is discussed for the design of a sensor network deployed in a spatial domain that is supposed to be used while detecting changes in...
This paper presents a procedure of fault detection and isolation of proton exchange membrane (PEM) fuel cell based on its mathematical model by nonlinear analytical redundancy approach. The model is simplified into five nonlinear state equations representation. The transient phenomena captured in the model include the compressor dynamics, the flow characteristics, mass and energy conservation and...
This paper focuses on sensor fault detection and isolation (FDI) problem by enhancement of a parity space approach. Indeed, faulty sensor can degrade overall system performances, especially in electrical drives where inner current control loops are very fast and based on sensors outputs. Parity space theory is investigated in the context of general FDI algorithm generation for second-order systems,...
