Explores some new applications that are based on linear quadratic (LQ) theories to the optimal guidance problems. New guidance laws that are based on LQ one-sided optimization theory and on differential game theory are introduced, and old guidance laws are rederived and set in a more general framework. Written specifically for engineers, the problems are formulated and solved with state-space representations in an informal mathematical style. The disk includes the source code listings of the MATLAB and MAPLE subroutines for the analytical and numerical solutions to the optimization problems in the text.
