This thesis aims at developing control design methodologies and implementation technologies for an electric injection molding machine control system. This type of electric injection molding machine is an innovationally mechatronic product which is constructed by a synthesis of precision manufacturing, servomotor driving and advanced digital control. The controller for the machine is devoted to achieving motion control, temperature control, PLC control, man-machine interfacing, injection speed tracking and holding-pressure control. A novel, DSP-based, proportional-integral (PI) and feedforward speed profile control is presented based on motor torque control mode in order to accomplish speed profile tracking for the machine. To have good control at the holding-pressure stages, a modified gain scaling PI control based on sliding mode control theory is proposed to improve the switchover control of fill-to-packing without overshoot. Several experimental results have proven that the proposed methods together with the built system prototype are feasible and effective. These developed technologies are expected to be useful in improving and promoting the current and future control technologies for electric injection molding machines.
