Abstract
Numerical simulation of a two-dimensional airfoil controlled by jets near the trailing edge is investigated. This simulation couples the Reynolds-averaged Navier Stokes equations with Euler’s equations of rigid-body motion and an active control system. Robust control design techniques were used to develop a controller for tracking altitude commands. Simulation of the controller with the coupled system showed good tracking performance for a step input command in altitude. However, the linear model was unable to capture the nonlinear nature of this system producing mild oscillations in the attitude, pitch rate, and vertical velocity of the airfoil.
