Design and Test of the Control System for Adaptive Wing

On the basis of adaptive control theory,the design strategy proposed by us can be used to solve adaptively the problem of time-varying parameters generated by the wing in flying.In the full paper,we explain in detail our design strategy;in this abstract,we just add some pertinent remarks to listing the one topic of explanation:(1) adpative control strategy;the subtopics of topic 1 are the control requirements of adaptive wing(subtopic 1.1),the strategy of adaptive control system(subtopic 1.2),and the analysis and evaluation of control strategy(subtopic 1.3);the subsubtopics of subtopic 1.2 are the modelling of time-varying parameters(subsubtopic 1.2.1) and the design of adaptive control law(subsubtopic 1.2.2);under subsubtopic 1.2.2,we give eqs.(7) through(17) in the full paper,most of eqs.(7) through(17) are taken from the open literature,but eqs.(13) and(17) are derived by us;eq.(17) is particularly worth being paid special attention;under subtopic 1.3,we state that,using dynamic data modelling and input-constrained control algorithm,the controller is expected to perform well in stability and robustness and it is expected to converge fast in the test process.Finally we give our results for tests on an aircraft wing in Figs.3 through 11 in the full paper.These results show preliminarily that the controller for the adaptive wing is reliable and feasible and also performs well on-line.
