The application of specific optimal control to the design of desensitized model following control systems

The concepts of specific optimal control, trajectory sensitivity design, and perfect model following are integrated to develop a general design technique for the linear servo model following problem. Control laws designed by this procedure are characterized by partial state feedback, perfect model following when theoretically possible, relative insensitivity of the compensated plant to mathematical modeling inaccuracies, and plant-model realignment in the presence of state disturbances. The feasibility of the design technique is demonstrated by the design of a nontrivial aircraft control problem.
