摘要：

In this paper, a new technology for control of next generation airplanes with virtual aerodynamic wing shaping using synthetic jet actuators is presented. The synthetic jets modify the local flow using a voltage driven vibrating diaphragm. The actuator array outputs are controlled by modulating the peak-to-peak amplitude of the input voltage. Nonlinear parameterized models of synthetic jet actuators whose parameters are chosen from a baseline model are presented. Adaptive inverse arrays are employed for canceling the effect of the jet nonlinearities. A state feedback control law is used for controlling aircraft dynamics. Parameter projection-based adaptive laws are used to ensure desired closed-loop stability and asymptotic tracking. An adaptive inverse scheme that is robust to modeling errors and parametric uncertainties of the synthetic jets is also presented. Copyright © 2006 by University of Virginia Charlottesville.
