Abstract

This paper proposes a method for detecting faults generated by increased loads in a class of mechanical control systems. It is considered that the load (input disturbance) is unmeasurable, only its bounds corresponding to normal operation are known. To solve the fault detection problem, a detector was proposed for a class of linear control systems that can be implemented with low computational costs. The method is applicable for electro-hydrostatic actuators (EHA) with unknown load. The proposed fault detection approach is validated through simulations for jamming detection of aircraft control surfaces driven by EHA.
