Buildings.Fluid.HeatExchangers.Examples.WetCoilCounterFlowPIControlAutoTuning
Model that demonstrates the use of a heat exchanger with condensation and with autotuning PI feedback control
Information
This example is identical to Buildings.Fluid.HeatExchangers.Examples.WetCoilCounterFlowPControl except that the PI controller is replaced with an autotuning PI controller.
The autotuning is triggered twice.- The first one occurs at 100 seconds and it completes successfully, with the tuned PI parameters taking effect at 215 seconds.
- The second one occurs at 2100 seconds and it fails because the setpoint changes at 2400 seconds. Thus, the PI input gains remain the same as the one from previous tuning.
