The paper focuses on the development of techniques for solving control
engineering problems by applying heuristic search methods. Two main c
ontributions of the work are: theoretical development of heuristic opt
imal control and its application to real engineering problems. In the
sense that intelligence is an ability which maximizes the possibility
of reaching a goal in an uncertain environment, heuristic optimal cont
rol is an intelligent control method. The paper provides necessary not
ation, proofs of the basic theories, and examples of heuristic optimal
control.
