In this paper, a quaternion-based finite-time sliding mode attitude controller is designed for a spacecraft performing high-thrust orbital maneuvers, with cold gas thrusters as its actuators. The proposed controller results are compared with those of a quaternion feedback controller developed for the linearized spacecraft dynamics, in terms of settling time, steady-state error, number of thrust...

The anti-skid braking system of unmanned aerial vehicle has the characteristics high-order nonlinearity, strong coupling, and time-varying parameters, which will seriously affect taxiing performance vehicle. This paper proposed a cascaded fast terminal sliding mode control method for electric system, can accurately track optimal slip rate ensure stability system. First, model is established, ge...
