Abstract
Leakage and increased friction are common faults
in hydraulic cylinders that can have serious consequences if
they are not detected at early stage. In this paper, the design
of a fault detector for a nonlinear hydraulic mechanical system
is presented. By considering the system in steady state, two
residual signals are generated and analysed with a composite
hypothesis test which accommodates for unknown parameters.
The resulting detector is able to detect abrupt changes in
leakage or friction given the noisy pressure and position
measurements. Test rig measurements validate the properties of
residuals and high fidelity simulation and experimental results
demonstrate the performance and feasibility of the proposed
method.
