Digital Feedback Control Of Servomotor Via Fiber OpticsOptoelectronic system effects closed-loop control of shaft angles of servomotors. Includes full-duplex fiber-optic link carrying feedforward and feedback signals, between digital motor-control circuits and modules containing motor-power-switching circuits. Fiber optics provide immunity to noise and rapid transmission of data. Features particularly advantageous in robots.
