Abstract:

This paper presents a benchmark study on fault diagnosis of electrohydraulic servoactuators (EHSA). EHSA are considered to be affected by faults and disturbances. The linear mathematical model of the EHSA is given. Two different design methods for fault diagnosis are studied. The first method considers the strategy of parity space design, and observer-based implementation, in which a perfect disturbance decoupling is achieved. The second method considers the linear EHSA model with polytopic uncertainties in order to design a residual signal using fault detection filter (FDF) theory, and to calculate a threshold. Linear matrix inequalities (LMI) are used to obtain the problem solutions
