The paper studies this global output regulation of a class of two order Port-Controlled Hamiltonian Systems with mismatched disturbance by a composite control method. By combining the damping injection, the finite time disturbance observer (FTDO) and the coordinate transformation techniques together, the composite controller is developed. The novel idea is to design a coordinate transformation to...
To extend cable-stayed utility longevity and reduce the frequency of vortex-induced vibration. Firstly, this paper designs a new-style cross-section shape of the stay-cables' casing with the help of aerodynamics. Secondly, it establishes its expression making use of CFD, afterward, it compares the new model with existing and gets the new modle can avoid coming into being significantly vibration. It...
Unstable periodic orbits of the chaotic passive compass-like biped robot which is an typically impulsive dynamical system are stabilized by using energy-shaping control. Because of impossibly instantaneous regulation of the angular and angular velocity of the passive compass-like biped robot, energy damping control with reference energy calculated by using impulsive control is supposed. Sufficient...
