Surely the red line (output) should be decreasing to match the setpoint (blue) instead of constantly increasing? |

Dear User,
When your error signal is positive in PI controller with positive gains and an acceptable integration Time, your outputs signal (red line)should be increasing.This is the demand to put more energy into system to increase temperature.In case of reaching to set value or overshoot(PV>SP), the output will be decreasing. Sample program: field simulation for PID CompactI hope it helps, hdhosseini
