报告摘要:System faults such as component damage and actuator failures can cause large system structural and parametric uncertainties which challenge existing feedback control techniques. For performance-critical control system applications such as aircraft, spacecraft, power systems, cyber physical systems, the ultimate goal of resilient control is to ensure desired system performance such as tracking or optimality, in addition to stability, despite the presence of uncertain system faults.

In this talk, we will describe some main features of resilient control systems and demonstrate how adaptive fault accommodation techniques increases system resilience by adaptively compensating the effects of uncertain actuator failures and structural damage, to maintain desired system performance. A unique issue is to handle system faults without knowing their occurrence time and location and their signal components in an uncertain dynamic system. We will address some related technical issues including research motivation, characterization of resilient control systems, modeling of faults, system invariance for adaptive fault accommodation, adaptive actuator failure compensation, and adaptive control for systems with structural damage. We will use examples from aircraft flight control systems to show adaptive fault accommodation designs can ensure desired system resilience to uncertain faults.
