In this paper, a simple mathematical model was proposed to answer such a question: what’s the relationship between the finger pressing position and the corresponding pitch for stringed instruments? Furthermore, we compared the theoretical results with measurement results which were obtained from a guitar to prove that the model we propose is reliable. Result shows that relative errors of theoretical results and measurement results are from 0.18% to 1.8%. The mathematics model is more concise, direct and clear than physical model.

This paper deals with the problem of designing low sensitivity memory H ∞ state-feedback controllers for linear discrete-time systems with time delay. The time-delay factors are known constant scalar. The aim of this paper is to design a memory low sensitivity sate feedback control law such that the closed-loop system is asymptotically stable for all admissible time-delays and multiplicative controller coefficient variations in the framework of coefficient sensitivity theory. A new sufficient condition based on linear matrix inequality (LMI) technique for the existence of such controllers is formulated.
This paper studies the problem of designing insensitive H∞ output-feedback controllers for linear discrete-time systems. The designed controllers are insensitive to additive/multiplicative controller coefficient vari...

This paper proposed a novel grasper for a novel master-slave robotic catheter navigation system in Vascular Interventional Surgery (VIS). The developed novel grasper can imitate the catheter grasping motion of the surgeon during VIS. The grasper is a key factor to drive the catheter into the vessel accurately. It adopts a common structure like the pliers, which can guarantee that the catheter can be clamped on the same axes with other via hole. The clamping force can be adjusted by the screw through changing the entered length of the screw to change the compression length of the spring. The clamping system consists of two graspers both master side and slave side respectively. The graspers clamp the catheter just like the surgeon's hand and the clamping method of the grasper imitates the surgeon's operation. The performance evaluation experiments of the novel grasper were done. The experimental results indicated that the grasper was effective to clamp catheter tightly to increase accuracy of surgery, which can satisfy the design demand.
