Automatic startup operation of plastics extruder by flexible intelligence machine control

摘要

In process control, the need of multitype small-lot production becomes strong. But, due to strong nonlinearity and abrupt changes of plant dynamics, attempts to introduce quantitive model of plants and promote automated operations have been hindered. For this problem, we proposed the concept and the structure of the FIMC (Flexible Intelligence Machine Control) which is a controller with functions for acquiring control knowledge about the operation know-how from the data furnished of expert operators in manual operation control hysteresis and eventually in automating operations based on control knowledge. In this paper, we show the design method and effectiveness of the FIMC applied to the startup operation of the plastics extruder.
