Quadrotor is a strong coupling, under actuated complex system with multi inputs and multi outputs. In this paper, the quadrotor UAV model was presented at first. In order to control the position and attitude respectively, a nested loops control strategy was employed. The full control was divided into two parts, i.e. position control and attitude control. Both a PD controller and a fuzzy adaptive PD...
When the astronauts are running on the astronaut treadmill for healthy exercise, their impact force will have serious disturbances on almost all the on-orbital science experiments. To solve this problem, a parallel passive vibration isolation system is designed for the astronaut treadmill. The proposed passive vibration isolation system can also restrain the high-frequency disturbance aroused from...
