An Intelligent Control Strategy for the Spray Forming Process
Abstract
A control system incorporating a fuzzy logic inference engine and optical sensors has been developed for the spray forming facility at the David Taylor Research Center. An imaging system employing laser illumination and a high speed CCD camera provides critical on-line preform surface roughness and rate of growth information. A fuzzy logic controller utilizes a rule set to translate visual information into a form that can be reviewed by the conditional statements of the rule base. A high performance manipulator and motion controller have also been incorporated into the spray forming system. This discussion includes development of optical sensors and integration of advanced control systems to determine and activate required corrective actions to the spray forming process parameters.
