Using a compressor to simulate the PID control of a fan
Thread Content
I’d like to ask an expert: Why, when using a compressor to simulate a fan and a pressure curve is input, does the pressure increase not change with the compressor’s speed? In my PID control system, the PV input represents the fluid pressure behind the fan, while the OP represents the fan’s speed. Why doesn’t the fan speed change, no matter how the pressure changes?
It’s not done correctly; it’s also possible that your PID parameter values are set too high, which results in little effect
