| Abstract: | Used the air flow as the main parameter, applied S7 - 300 PLC and inverter as the controller, when the air flow changed, the PID parameter is adjusted. The frequency of inverter is changed, and then motor speed of the ventilating fan is regulated. By monitoring every parameter, the ventilating fan runs safely. Resuits indicate that using inverter to regulate motor rotation speed is an ideal control method which can save electric energy effectively. |
