Dear TRNSYS users,

I am using PID controller to modulate the damper to control natural ventilation coming to a space through an atrium. The problem is that control output constantly osciallates from 0 to 1, but never stabilizes at a certain value between them. I tried to simulate with different time steps, but the results did not change.

Could you help me what possible problems and solutions are for this matter?

Thanks,

Yeonsook
