Abstract: Aiming at the problems, such as low control precision, lag in response, and insufficient automatic monitoring, the electric control system in ordering machine was improved.The water added feedforward cascade control model was established, and the casing was timely revised with batch control technology.The monitoring program developed with CITECT could exchange data with PLC and perform real-time production monitoring.The improved system featured higher control precision and reliability, was flexible in operation, and offered satisfied processing quality.
