Abstract

This paper presents an L1 adaptive controller for pressure control using an engine bleed valve in an aircraft air management system. The air management system is composed of two pressure-regulating bleed valve, a temperature control valve, a flow control valve, and a heat exchanger/precooler. Valve hysteresis due to backlash and dry friction is included in the system model. The nonlinearities involved in the system cause oscillations under linear controllers, which decrease component life. This is the driving motivation for the use of adaptive control. The paper presents simulation results using the adaptive controller, and compares them to those using a PI controller.
