The PID Set point is to be determined from the Input test_envelope (this is a sub task which will take the DUT_temperature input and work out a multiplier for the Kp parameter as described in the test_envelope task) Process Variable to come from the DUT_temperature input. PID controller (using standard PID vi from LabVIEW library) to control a heater according to a test_envelope (see description in the inputs section), PID loop parameters (Kp Ki & Kd) set internally to the VI as constants (set at LabVIEW defaults) and a multiplier.
