Abstract
A protective device for an electronic unit on a space exploration vehicle. A Laplace transform calculation unit generates a Laplace transform of an electronic unit state. A system parameter identification unit identifies system parameters based on the Laplace transform of electronic unit states. A Fourier transform calculation unit generates a ratio of the ground contacting mechanism state to a highest dominant frequency of the measured electronic unit state. A critical travel speed calculation unit generates a critical travel speed based on the identified system parameters. A calculation unit for threshold of travel speed generates a threshold of a travel speed based on the critical travel speed. An autonomous motion controller generates a control signal that drives the space exploration vehicle based on the threshold of the travel speed.
