Control laws with hierarchical switch logic to accomodate EME-induced sensor failures

Abstract

In this paper the issue of fault tolerance of flight control systems to sensor failures due to harsh electromagnetic environments is addressed. Severe consequences of these failures can be avoided or at least mitigated to a large degree by using fault tolerant software design. An array of control laws anticipating sensor failures is designed. A hierarchical logic to switch between these controllers is programmed, allowing effective and rapid reconfiguration of the system to accommodate for failed sensors.
