Comparison of a New Frequency-limited Adaptive Control Architecture with Standard and State Predictor-Based Adaptive Controllers
Abstract
This paper presents a frequency-limited adaptive controller design for an aeroelastic generic transport model. Specifically, the proposed framework consists of a new reference system and an adaptive controller. The proposed reference system captures a desired closed-loop dynamical system behavior modified by a mismatch term representing the high-frequency content between the uncertain dynamical system and this reference system, i.e., the system error. It is shown that this mismatch term allows limiting the frequency content of the system error dynamics, which is used to drive the adaptive controller. This key feature of our framework yields fast adaptation without incurring high-frequency oscillations in the transient performance. Numerical examples are provided to demonstrate the effcacy of the proposed design for the aeroelastic generic transport model in the presence of degradation in the control effectiveness.
