Compound Control

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.

Manipulator Control

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.
