EK3114 Automatisering og vannkraftregulering

Demo:
Automatic model adaption to air heater (in LabVIEW)

The logfile airheater_logfile.lvm stems from an experiment on the air heater. The file containes three colums of data:

Time, t [s]
Control signal, u [V], manipulating the heating element.
Pipe outlet temperature response, T_out [grader C].

The top-level VI in the LLB-file air_heater_model_adaption_brute_force_optim_240916.llb implements adaption of the following model parameters from the data in the above logfile:

Gain K [C/V]
Time-constant T [s]
Time-delay tau [s]
Environmental temperature Temp_env [C]

The teacher will run the VI in the lecture. (You can of course try it yourself, after you have downloaded both the LVM file and the LLB file.)
