Abstract: A non linear model of active control of the landing gear has been established. According to the state equations and a reasonable objective function, the comprehensive performance of landing gear is optimized. By numerical simulation, the taxiing performance of an active control system landing gear and that of a passive system landing gear are compared.

Key words: landing gear, active contr ol, non- linear vibration, t axiing per formance
