摘要：

A multiloop control system for a pilot-scale membrane separation process is designed and evaluated. The process employs hollow fiber membrane modules and is representative of air separation systems in industry. The decentralized control system originally consists of five PID controllers which regulate feed flow rate and pressure, permeate pressure, suction pressure, and module temperature. This configuration yields poor performance as a result of interactions between the feed flow rate and feed pressure controllers. By disabling the flow rate controller and proper tuning of the remaining control loops, satisfactory control is achieved during 4 days of continuous operation.
