This paper investigates the robust controller of an electric power steering system. The design methods of the robust Hinfin mixed sensitivity controller are researched by the transfer functions model of EPS system, based on the classical PI current loop. The theoretical analysis and simulation experiments indicate that the proposed controller can improve the capability of low frequency noise enhancement...
Micro operation assisted by miniature mobile robot system has become a research hot in robotics and micro operation domain. In this paper, a newly developed micro operation oriented five D.O.F. (degrees of freedom) miniature mobile robot system is presented. By comparing it with other miniature robot systems, the main improvements of this design are macro/micro dual driven, embedded hardware, wireless...
A newly developed five D.O.F. (degrees of freedom) miniature mobile robot system is presented. It consists of a moving positioning module with macro/micro dual driven modes and a three rotational D.O.F. spherical micromanipulator module. With the macro motion mode, the robot is a typical wheeled mobile robot, which is driven by two small size brushless DC motors. With the micro motion mode, based...
