Abstract: Abstract：An orthogonal array experimental design method is developed to optimize the control system parameters of a freefloating space robot manipulator. The experiment results show that it is very quick and precise in approaching the appropriate value of every control parameter with the orthogonal array experimental design method. The method is very useful for optimizing control parameters of complex systems. For example, L81(340) orthogonal array can realize the optimization of fourteen adaptive control parameters which are selected randomly.
