L1 Adaptive Control for Switching Reference Systems: Application to Flight Control
Year: 2019
Type: article
Abstract: This paper presents a framework for design and analysis of an L 1 adaptive controller with switching reference systems. Use of switching reference systems allows the desired behavior to be scheduled across the operating envelope, which is often required in aerospace applications. The analysis uses a switched reference system that assumes perfect knowledge of uncertainties and uses corresponding non-adaptive controller. Provided that this switched reference system is stable, it is shown that the closed-loop system with unknown parameters and disturbances and the L 1 adaptive controller can behave arbitrarily close to this reference system. Simulations of the short period dynamics of a transport class aircraft during the approach phase illustrate the theoretical results.
