“…The absence of contact between an AMB and rotor avoids wearing and the need of lubrication, in addition, AMB dynamics is relatively easy to control [21]. For this, many researchers have reported results about showing the viability for AMB application in vibration control of rotating machinery since the 1990's [16,26] until recent days [1,13,20,28]. Piezoelectric actuators are other devices with an increasing application in rotor systems, they represent an alternative because their main characteristics: very precise movement, compact, high force, low energy consumption, quick response time, no electromagnetic interference.…”

“…In terms of sliding modes, although LPV based sliding mode control schemes were proposed a decade ago (see for example [13,14]), until recently there were no LPV based sliding mode observers which had appeared in the literature. However recently higher order sliding mode methods have be employed to develop so-called interval observers [15], and an LPV observer has been proposed in a fault detection context [16].…”

This paper describes the development and the evaluation of a robust sliding mode observer fault detection scheme applied to an aircraft benchmark problem as part of the ADDSAFE project. The ADDSAFE benchmark problem which is considered in this paper is the yaw rate sensor fault scenario. A robust sliding mode sensor fault reconstruction scheme based on an LPV model is presented, where the fault reconstruction signal is obtained from the so-called equivalent output error injection signal associated with the observer. The development process includes implementing the design using AIRBUS's so-called SAO library which allows the automatic generation of flight certifiable code which can be implemented on the actual flight control computer. The proposed scheme has been subjected to various tests and evaluations on the Functional Engineering Simulator conducted by the industrial partners associated with the ADDSAFE project. These were designed to cover a wide range of the flight envelope, specific challenging manoeuvres and realistic fault types. The detection and isolation logic together with a statistical assessment of the FDD schemes are also presented. Simulation results from various levels of FDD development (from tuning, testing and industrial evaluation) show consistently good results and fast detection times.

“…That said, notable exceptions in the area of control are described in [36], [31]), and recent work [15] has applied higher order sliding mode ideas to LPV systems for so-called interval observers. Recently, the work in [3] explored the potential of using sliding mode techniques for LPV systems, specifically for FDI with fault reconstruction.…”

This paper presents a robust FDI scheme using a sliding mode observer based on an LPV system, with fault reconstruction capability. Both actuator and sensor fault reconstruction schemes are considered which possess robustness against a certain class of uncertainty and corrupted measurements. For actuator fault reconstruction, the input distribution matrix (associated with the actuators being monitored) is factorized into fixed and varying components. LMIs are used to design the key observer parameters in order to minimize the effect of uncertainty and measurement corruption on the fault reconstruction signal. The faults are reconstructed using the output error injection signal associated with the nonlinear term of the sliding mode observer. For sensor fault reconstruction, the idea is to re-formulate the problem into an actuator fault reconstruction scenario so that the same design procedure can be applied. This is achieved by augmenting the original system with the filtered sensors being monitored. Simulations using a full nonlinear model of a large transport aircraft are presented, and show good fault reconstruction performance.
