Abstract

A low cost, Digital Signal Processor (DSP) based optical position sensor and control system was developed on this work for the vibration control of flexible structures and assembly workcells. This system is based on Texas Instruments' TL220/230 programmable light-to-frequency converters which are interfaced to a TI TMS320C25 DSP. The sensor is a standard 8-pin dip powered by a single DC supply so that it may be mounted on robots or other industrial machines without causing any loading or perturbations. Effects of additive noise are also minimized as the sensor output is pulse position modulated TTL signals.
