Tuning of PID controllers for water networks- different approaches

摘要

The proportional integral derivative (PID) controller can improve control of water distribution sys-rnterns by reducing leakage, maintaining pressure, and controlling flow in entire networks. Using the PID controller, targets can be achieved very fast without creating undue transients. Such optimum performance, though, depends on the fine-tuning of controller'srngains (parameters). This study compared three methods used to fine-tune the PID controller in different test situations involving flow and level control to different reservoirs. These gain-tuning methods were tested by simulations on different field problems with satisfactory results.
