Laddermill flight control problem with closed loop
is considered in this paper. Laddermill is an alternative concept
for energy production using high altitude kites. The kites have
been simulated as rigid bodies and the cable as a thin elastic line.
Euler angles and cable speed are controls. Flight control is
written as a fusion of two approaches: design of experiments and
stochastic optimization. Such combination ensures finding global
optimum for any reasonable number of parameters and
objectives in a reasonable time while also collecting some
information about sensitivities – these two features are much
harder to achieve by other means. Robustness has been
formulated as an additional objective. We found the system very
steady despite big variations of wind velocity. The resulting
optimal trajectories can be also used as a first iteration for open
loop control algorithms. The methods used can be also employed
in wide range of wind energy applications.
