Optimal Anticipafory Control of Ram Velocity in Injection Molding.
MetadataShow full item record
This paper discusses a computer control system for ram velocity of an injection molding machine using optimal state feedback based on the linear quadratlc control theory. A new approach for the selection of appropriate weighting matrices is presented in this context. The simulation results reveal that the optimal controller has improved performance over the conventional PID controller presently used, having faster speed of response, significantly better and the core storage requirements would allow implementation even on a small online computer.
