Abstract : Three competing adaptive lateral control systems for an entry glider are evolved and compared. In the course of the evolutionary process, entry vehicle dynamic characteristics are examined and approximate literal transfer functions are determined; some handling qualities requirements are postulated and competing systems consistent with these requirements are indicated; the systems are formulated and studied using multiloop analysis techniques where appropriate. The systems evolved all include a function of bank angle fed to aileron, as an outer-loop. Detailed consideration is given to the functional form of the adaptive adjustments required for equalization and gain. (Author)
