*† ‡ § ¶ # This paper describes a repetitive-learning algorithm that extends the capabilities of a wind tunnel wire suspension system. The algorithm permits the simulation of free-yaw flight in a test fixture that provides controlled but not free yaw motion. The apparatus is a sixcable suspension apparatus with bearings to provide free pitch and roll. Six hydraulic cylinders also provide a means of controlling yaw via cable tension, but free yaw could not be implemented due to geometric constraints. The new control algorithm can simulate free yaw by repeating a particular maneuver, each time measuring the restraining moment at the model attachment point. After each iteration, the controller generates a new maneuver yaw trajectory, repeating the process until the restraining moment is near zero. Wind tunnel tests will be completed in the coming months. However, we have performed – and show herein – a set of simulations that demonstrate the function of the control algorithm. |
