A class of dual-rate system with a fast control updating rate and a slow output sampling rate is considered. Lifting technology is applied to derive lifted state space model and a subspace equation for dual-rate systems. From the subspace equation, the dual-rate predictive control law is calculated from a set of input/output (I/O) open-loop experimental data and, thus, this approach is data-driven...
A kind of auxiliary device for ankle rehabilitation based on ball pin vice is designed and developed. The device has two degrees of freedom, but it can achieve approximatively the three-dimensional movement of the bionic ankle. When the device is used for auxiliary ankle rehabilitation, which only leads ankle to rotate not to move, and its structure is very simple. The ball pin pairs are adopted as...
This paper presents an automated handling approach of two-dimensional nanomaterials using a robotic setup inside a high-resolution scanning electron microscope. Applying image processing of the visual feedback provided by the electron microscope, a fully automated sequence is developed to align a robotic driven force sensor with sub micrometer accuracy and to conduct nanoindentation measurements on...
