Serial link mechanism driven by pneumatic artificial muscles (PMA) usually adopts tendon transmission. In many cases, the torque and position couplings between each joint are obvious, which would affect the control performance. By analyzing the position equation of tendons, this article proposes a decoupling control method for PMA-driven serial link mechanism. First of all, the coupling matrix is...
Turbulence mitigation refers to the stabilization of videos with nonuniform deformations due to the influence of optical turbulence. Typical approaches for turbulence mitigation follow averaging or dewarping techniques. Although these methods can reduce the turbulence, they distort the independently moving objects, which can often be of great interest. In this paper, we address the novel problem of...
Vortex levitation can achieve non-contact handling by blowing air into a vortex cup through a tangential nozzle to generate a swirling air flow. In this paper, its dynamic characteristics are analyzed through dynamic pressure response, and a dynamic modeling is developed and verified experimentally. First, we observe the pressure dynamic response inside the cup by making the cup and the work piece...
Pressure ripple in electric power steering (EPS) system can be caused by the phase lag between driverpsilas steering torque and steer angle, the nonlinear frictions, and the disturbances from road and sensor noise especially during high frequency maneuvers. This paper novelly applied the robust fuzzy control method of active reduction of pressure ripple for EPS system, which achieves remarkable progress...
