Basic Research in Digital Stochastic Model Algorithmic Control.
Abstract
This report presents the results of basic research in Model Algorithmic Control (MAC) with application to flight control systems. MAC is a new digital control design approach which relies on the following features: (1) an internal model of the system to be controlled; (2) a reference trajectory description of desired closed loop behavior; and (3) an on-line optimization of future control inputs to produce the desired performance. MAC is well suited to the new generation of microprocessors, and is applicable to a wide variety of aerospace problems. The purpose of this report is to explore the theoretical foundations and robustness of MAC and to examine its application to flight control problems. A missile attitude control simulation is chosen as a typical control design problem and used to demonstrate the application of MAC theory. The major conclusion of this report is that MAC is a very flexible, powerful and promising technique for linear multivariable control design. Its theoretical properties of optimality, convergence, robustness and stability are verified by simulations of the missile attitude control example. It is recommended that future studies of MAC concentrate on its extensions to the adaptive case and on flight test demonstration of MAC concepts. (Author)
