Passivity-Based Robust Control with Application to Benchmark Active Controls Technology Wing

A passivity-based robust control design methodology is presented. A brief review of the stability results is given for passive linear and nonlinear systems followed by four different passie cation methods for rendering nonpassive systems passive. The robust control methodology via robust passie cation is demonstrated by application to the Benchmark Active Controls Technology subsonic wing. The controller design is shown to provide robust stability and satisfactory performance.
