Short summary
Gyro-pendulums are usually used to stabilize the firing of guns on warships or tanks or to navigate cars and aircraft. The stability of the gyro-pendulum is a classical problem in dynamics and control. Moreover, the bounded noise is real in nature, which affects the operation of the dynamical system and even its stability. Our research results on the stochastic stability of gyro-pendulum systems have a good guiding effect for the actual operation of the system and engineering application value.
