Merging conventional and optimal control techniques for practical missile terminal guidance
Abstract
This investigation has focused on missile terminal guidance by optimal control techniques. A comparison with well-known classical guidance techniques is included. Useful relationships have been derived to show how to use performance index terms to limit terminal errors. Comparative characteristics derived from terminal weighting and terminal constraints are shown. Results have been for cruciform and bank-to-turn steering. Optimal results show compensation for control lags and produce smaller steering error than classical guidance. Techniques to facilitate numerical convergence of solutions have been used, and guidelines for their use evolved.
