This paper presents a new design for a torque sensor based on a differential capacitive technology. An arc-radial mechanism is adopted to achieve high rotary/radial motion linearity. Kinematic model of this assembly is derived via vector loop equations. A nonlinearity index is formulated and practical kinematic constraints are imposed. Results show that very high kinematic linearity could be achieved...
This paper describes the implementation for a basic fuzzy logic controller in Very High speed integrated-circuit Hardware-Description Language (VHDL). It is not intended as an introduction to fuzzy logic control methodology; instead, we try to demonstrate the implementation of a fuzzy logic controller through the use of the VHDL code. Use of the hardware description language (HDL) in the application...
A novel design is presented for a noncontacting torque sensor based on differential capacitive sensing principles. Although, developed initially for automotive applications, the sensor and sensing techniques presented are applicable to a wide range of applications in the industrial, transportation, and aerospace and defense industries
A "state-of-the-art", low cost, lightweight Exciter/Local Oscillator/Down Converter (EX/LO/DC) subsystem is presented for use in airborne applications. It plays a triple role of providing TWT excitation, local oscillator drive and dual channel RF-IF conversion. The overall subsystem design together with experimental results is presented.
