Output Feedback Variable Structure Adaptive Control of an Aeroelastic System

摘要: The paper presents an application of the variable structure model reference adaptive control theory to aeroelastic systems with structural nonlinearity. Interestingly, design approach does not require any knowledge parameters system and nonlinear functions, only output feedback is used for synthesis systems. Control laws trajectory tracking pitch angle plunge displacement are derived. In closed-loop system, state vector asymptotically converges origin. discontinuous functions error, modulation relays generated on-line using bounds on uncertain certain auxiliary signals. Digital simulation results presented which show that in smoothly regulated zero spite uncertainty unmodeled feedback.
