Control Heating Rate of the Heaters with PID in Labview

[AlessioVirili]

Hello everybody

I have attached a Labview VI, rappresent the algoritm that I have developed. I ask some question: 

1) If is correct the reasoning that I follow;

2) If when I insert the real signal of the thermocouple, in the PIN "MESURED TEMPERATURE" the algorithm function correctly, or not.

3)In case the algorithm isn't correct, can I know why, and the principal elements that I have to modify.

Thank you in advance for the response.

Greetings.

1. It seems to be correct, more or less. Using the examples coming with LabVIEW is always a good idea! (Your "setpoint profile" has no data, so you missed to input the needed profile data…)
2. The VI is still correct then. In case of using real sensor data you don't need the "plant" subVI anymore, it's just used for simulation purposes…
