DRIVING METHOD AND DRIVING DEVICE FOR DRIVING A POLYPHASE INVERTER
(2010-12-09)

;
CHEN, Keng-Yuan
A driving method for driving a polyphase inverter includes: receiving a reference input that includes a fundamental frequency component, and a previously generated feedback signal; generating an error signal that corresponds to a difference between the reference input and the previously generated feedback signal; attenuating the error signal to the minimum; generating an optimum signal; quantizing the optimum signal; and generating driving signals that correspond to the quantized optimum signal. A driving device that implements the driving method is also disclosed.

A glove puppet manipulating system comprises a control module for generating control signals base on movements of human hand and a robot electrically connecting the control module installed inside a glove puppet. The robot has a body manipulating apparatus disposed on a foundation to manipulate the body of the glove puppet to rotate, a pair of hand manipulating apparatuses disposed on the body manipulating apparatus to manipulate the hands of the glove puppet to swivel, and a head manipulating apparatus interposed between the hand manipulating apparatuses on the body manipulating apparatus to manipulate the head of the glove puppet to nod.
