This thesis proposes a new virtual sensing approach for on-line monitoring and regulating process variables of injection molding. Based on the nonlinear observer theory, virtual sensors estimate process behavior using easily obtained measurements of machine variables by exploiting their dynamic interaction. A nozzle pressure virtual sensor for filling process with an actual mold was developed. Results of experimental evaluation on a commercial injection molding machine confirm effectiveness of the proposed virtual sensing approach.
