Experimental Evaluation of Two Commercial Force Sensors for Applications in Biomechanics and Motor Control
نویسندگان
چکیده
The objective of this work was the comparative analysis of two commercial force sensors, the FSR sensors (Interlink Electronics, Camarillo, CA, US) and the Flexiforce (Tekscan Inc., Boston, MA, US), that can be attached to the palmar surface of the fingers to study the biomechanics of the hand during grasp and to develop rehabilitative devices such as closed-loop controlled hand neuroprostheses. The performance tests were performed with the sensors mounted on the thumb. The Flexiforce sensors showed better performance in terms of repeatability, linearity and time drift when mounted on a rigid substrate, and in terms of dynamic accuracy when mounted on the thumb. The FSR sensors showed better performance in terms of robustness.

Using an Appropriate Controller for Independent Current Control for Motoring of Force Windings of Bearing less Induction Motor
A bearingless induction machine has combined characteristics of induction motor and magnetic bearings. Therefore, the advantages are small size and low-cost. In the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. The suspension forces are generated taking an advantage ...
