Abstract : The design of fixed parameter flight control systems which produce acceptable closed loop bending characteristics has become increasingly difficult. This situation may be relieved through the use of an adaptive system which adjusts suitable parameters to achieve the desired performance. Two methods of improving the bending response through the use of model-reference adaptive techniques are presented. One method adjusts a compensation parameter in the flight control system. The second adjusts the effective bending sensed by a pair of rate gyros. The analytical development and the results of analog computer simulation of these systems are presented. (Author)
