摘要
介绍使用单片机进行PID控制的变频器调速系统 ,包括变频器控制方式和控制原理 ,实现了离心风机在气道稳流试验台上的恒压运转。
A system that uses the frequency inverter controlled by a microcomputer with PID controller to automatically adjust the speed of a centrifugal fan was introduced. And the constant-pressure operation of the fan in the inlet port steady flow test rig was realized.
