This article analyzes the shift factors of the descending node local time for sun-synchronous satellites and proposes a shift control method to keep the local t
Finite time stability and stabilization are studied for hy-brid dynamic systems. By combining multiple Lyapunov function and finite time Lyapunov function, a su
