It is important to close the control loop by providing tactile feedback to prosthesis users. An increasing number of researchers attempt to improve grasping performance by providing various types of tactile feedbacks. In our study, we improve the performance by a virtual environment in which subjects acquire two key grasping-related properties, including object's stiffness, economically holding power...
A novel transient differential protection based on approximation and z-transform theorems is proposed in this paper. The differential function relates to time is firstly approximated to convolution of the projection of differential operator and the function itself, subsequently the digital equation of transmission line is established. The z-transform is employed to obtain the solution of the sampling...
A novel scheme and algorithm of differential protection, which employs not only the power frequency component but the transient components based on distributed parameter line model, is proposed, as well as the distributed capacitive current is taken into account accordingly. The operating travelling waves Fcom and Bcom are defined as the forward and backward travelling wave that calculated with the...
