[TRNSYS-users] PID controller to modulate the opening of a damper

[Yeonsook Heo]

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
