Quick Force Balance Control Based on Equilibrium Point Movement of Tie-bar Temperature Controllers for Injection Molding Machine

Abstract

This paper focuses on the response deterioration of the force balance control system including the temperature control system due to the difference between heating and cooling speed. Our conventional method uses the limit error feedback method to suppress the windup of the temperature controller. The proposed method realizes the quick force balance control system using the equilibrium point movement controller. The experimental results show that the convergence time of the proposed method is faster than that of our conventional method, and the same response is obtained at different operating points.
