The paper investigates optical implementation of feedback control of mechatronic actuators. The goal is to analyze experimentally the feasibility of optical closed loop control using optical components for signal transmission and control loop implementation. The analysis is carried out for position control of an electric actuator. Angular position and velocity are measured with optical sensors. Measurement signals are transmitted through a fiberglass to an optical controller. Position commands from the optical controller are transmitted through a fiber glass as analog optical signals to a photodetector. A power operational amplifier serves a driver for the electric motor. This feedback controller configuration is designed to have extensive optical implementation and permits to investigate the level of complexity of the control laws which can be implemented optically. Experimental results, obtained using a LabVIEW for data acquisition and processing, illustrate the advantages and the limitations of the proposed optical implementation of a feedback controller for mechatronic actuators.
