PROPOSAL FOR STUDY OF ANALYSIS METHODS FOR NONLINEAR AUTOPILOT SYSTEMS
GENERAL DYNAMICS/CONVAIR SAN DIEGO CALIF
Pagination or Media Count:
This proposal is for the continuation of AF 336167371 to apply Russian analytical techniques to a typical pitch-rate autopilot and a pitch-rate autopilot with self evaluating loop. For the first autopilot the simplifications and assumptions for analysis are described and the method of solution of the equations is outlined. This autopilot will also be analyzed by an approximation method and use will be made of digital programs. In order to attach the second autopilot analytically, the approach will necessitate considerable research work in the realm of differential equations with time dependent coefficients for which approximate solutions are to be constructed by approved approximation methods. Some of the principles in the theory of approximation to which Russian mathematicians have made serious contributions will be used. This work will be supported and checked by analog and digital computational procedures.
