New natural observer applied to speed-sensorless DC servo and induction motors
(Ieee-Inst Electrical Electronics Engineers Inc, 2004)
A simple observer design technique with parameter adaptation is proposed for bounded-input bounded-output nonlinear systems. In this technique, no feedback is used in the observer but parameter estimations are considered ...
Design of a circular piezoelectric transformer with crescent-shaped input electrodes
(Inst Pure Applied Physics, 2003)
In this study, a new disk-type piezoelectric transformer design is proposed. The input side of the transformer has a crescent-shaped electrode and the output side has a focused poling direction. The electrodes and poling ...
A piezoelectric motor using two orthogonal bending modes of a hollow cylinder
(Ieee-Inst Electrical Electronics Engineers Inc, 2002)
This paper proposes a compact ultrasonic motor with low manufacturing costs, a simpler driving circuit, and scalability. The stator of the motor presented in this paper consists of a hollow metal cylinder, whose outside ...
