Abstract

This article proposes a holistic actuator fault tolerant control (FTC) scheme and validates it using the Japan Aerospace Exploration Agency's Multi-Purpose Aviation Laboratory (MuPAL-

$\alpha$

) Aircraft-in-the-Loop platform. The motivation for this work is to increase the technology readiness level associated with FTC technology, whilst improving the sustainability of future aircraft. The overall scheme uses bespoke sliding mode observers at a (local) individual actuator level to assess the health and the effectiveness level of each of the actuators. These estimates are aggregated and used in the control allocation mechanism to distribute a virtual control signal, designed using sliding mode control concepts, to the physical actuators. The overall closed-loop system stability is rigorously analyzed. The validation results show that the actuator effectiveness is well reconstructed and near nominal lateral-directional control performance is retained in the face of a class of actuator faults.

基于飞机在环验证的鲁棒在线控制分配FTC

本文提出了一种整体执行器容错控制（FTC）方案，并利用日本宇宙航空研究开发机构的多用途航空实验室（MuPAL-$\alpha$）飞机在环平台对其进行了验证。这项工作的动机是提高与FTC技术相关的技术准备水平，同时提高未来飞机的可持续性。整体方案在（本地）单个执行器级别使用定制的滑模观测器来评估每个执行器的健康状况和有效性水平。这些估计值被汇总并用于控制分配机制，以将使用滑模控制概念设计的虚拟控制信号分配给物理执行器。对整个闭环系统的稳定性进行了严格的分析。验证结果表明，在一类执行器故障情况下，执行器的有效性得到了很好的重构，并保持了接近标称的侧向控制性能。
