End-trajectory sliding mode control algorithm design of hybrid polishing robot based on nonlinear disturbance observer
Bo Sun, Xin Li, Feng Guo, Gang Cheng
Izvirni znanstveni članek
Oznake: hybrid polishing robots;dynamical model;sliding mode control;disturbance observer;trajectory tracking control;
The five-degrees-of-freedom (5-DOF) hybrid polishing robot is utilized for machining large optical mirrors. Since the existing kinematics control strategy does not meet high-precision control requirements, it is necessary to develop a dynamics controller to improve the operational performance of the ...

Oznake: step slider bearing;diamond-like carbon coating;DLC coating;interfacial slip;film thickness;coefficient of friction;
Experimental and theoretical studies have been completed in this paper to investigate the interface effect in the lubrication performance of a step slider bearing. Oleophobic fluorine-containing diamond-like carbon (F-DLC) coatings were prepared on the step slider to provide low affinity to lubricat ...
