Abstract
The regulation of a wind tunnel system using minimum control effort is considered. A theory enabling input-output models to be employed in the design process is outlined. The procedure is applied to the regulation of the airspeed within the tunnel working section enabling turbulent conditions to be replicated, using a Dryden wind gust generator. Optimum dynamic control with least control effort is achieved using a simple closed-loop structure. The penalties involved in selecting a non-optimum design are commented on.
