This thesis paper proposes the theory of compound control system to solve the problems of slow dynamic response, low system control precision, and reduced productivity in the process of speed regulation generated because of the frequency conversion renovation in the injection molding machine, and deduces it with mathematical modeling based on the qualitative theories of ordinary differential equations. My conclusions indicate that to adopt the compound control system can largely improve its steady state and precision, and increase its dynamic response speed.

Micro Structures

Micro-structure injection molding machine is mainly used for processing the plastic products in micron-size or with micro-structures. This paper focuses on the design and control of the clamping mechanism of micro-structure injection molding machine. Firstly, the deformation of the clamping mechanism was analyzed. The simulation results shows that the clamping force is 5.0051×105N, and it’s bigger than the design value 500kN. Secondly, the kinetic characteristic of the clamping was simulated by ADAMS software. The curves of the displacement, velocity, clamping force of moving platen were analyzed. Thirdly, the control model of clamping mechanism was established. And the LQR controller was designed and simulated by Matlab. The rise time is 0.010s, the settling time is 0.026s and the steady-state is 0.307m.

Design of manipulator control system for injection molding machine is raised in this paper. One servo motor and 32 pairs of IO of pneumatic actuators are applied to realize motion control towards manipulator. Functions such as precisely locating, multi-position start/stop and automatic mode operation are achieved through collaborative work of CPU and CPLD. Finally, the result indicates the control system is reliable and efficient.

Good control of plastic melt temperature for injection molding is very important in reducing operator setup time, ensuring product quality, and preventing thermal degradation of the melt. The controllability and set points of barrel temperature also depend on the precise monitoring and control of plastic melt temperature. Motivated by the practical temperature control of injection molding, this paper proposes MPC and IMC based control scheme. A robust system identification and control methodology is developed which uses canonical varieties analysis for identification and model predictive control for regulation. The injection molding process consists of three zones and the mathematical model for each of the zone is different. The control output for each zone controller is assigned a weight based on the computed probability of each model and the resulting action is the weighted average of the control moves of the individual zone controllers. Keywords: Injection-Molding Machine (IMM), IMC Control, Temperature Control.
