A Design Method of theH∞Sea-Wave Filter for the Helicopter Skimming Sea

摘要

To solve the problem that the traditional sea wave filter of helicopter skimming sea can not estimate the height precisely, a design method of Robust Sea-wave H∞filter based on LMI is proposed. The simulation results show that the sea-wave H∞ filter designed by using this method does not need the precise mathematic model of the helicopter and is insensitive to the changes of parameter of model and environments.
