| Abstract: | The paper introduces a kind of realization of frequency control about water supply system on the basis of VB and DLL, with computer controlling frequency converter and with frequency converter controlling three-phase asynchronous motor, which drives mechanism, automatic control and emulation of constant pressure water supply subsystem are achieved. The paper describes the system structure, working principle, control algorithm, manual/auto switch mode and digital filtering technique in detail. The system is launched into application and all performances suit to the demands. |
