An optimization methodology, algorithms, and computer program for
cable/lumped-body deployment system are developed for the design and installation of
sonar packages in deep ocean ranges. In addition, a methodology and algorithms for the
control of the system are proposed.
A penalty function is developed in terms of the system parameters and the
dynamic constraints are set up for the optimization of cable/lumped-body deployment
system. Deployment procedures and segmentations characterized by their initial and
terminal condition are proposed. Alternating Direction (ADM) and Modified Alternating
Direction (MADM) methods are employed for the optimum search. The optimization
algorithms are then implemented on a desk-top computer. The objective of the search
is to achieve the optimum vessel speed and cable pay-out rate that result in the minimum
penalty value.
Numerical examples are presented to test the robustness of the algorithm (ADM)
and the compute program capabilities. The results are compared to those of the MADM
method and the entire space search.
During actual installation, it is anticipated that randomness in the excitation will
cause sonar packages to miss the exact target locations. Thus a continuous correction
in the controllable parameters is necessary. Three alternative types of control algorithms
are presented for these reasons. / Graduation date 1993
