Precision Water Distribution Control of New Type Sewage Distributor

摘要

This paper focuses on the issues of uniform flow distribution control for sewage treatment devices. A novel method for uniform flow distribution was proposed, in which a new type sewage distributor employing two phrase stepper motors is integrated to replace the conventional one. The model of permanent magnet stepper motor is mainly discussed. A proportional-integral-derivative (PID) controller is designed for this new type distributor. The performance of general controlled system is simulated, compared by tuning the parameters. And the control system is evaluated in practical use.
