I am trying to change a part of a model of an air-conditioning system, and I need to know if it's possible to implement some sort of a temperature and RH varying input to simulate real-life outdoor temperature and humidity scenarios.
I am working on the pre-made model by MathWorks, the Refrigeration Cycle for air conditioning, inside the External Environment subsystem, I was thinking if I can replace parameters in reservoirs (MA) 'Air Outlet' and 'Air Inlet' with some sort of post-processed interpolated temperature series in excel format, in the seconds denomination, and let SimuLink run through those temperatures.
Currently for parameters reservoir_temperature and reservoir_RH they have taken values T_env and RH_env respectively, which are set in the preloadfcn callback to be constants. I was wondering if there is a way to dynamically change the values of the parameters during simulation, through my own dataset. I have loaded the dataset into my workspace, where my own T_env and RH_env are matrices 601201x2 in size (First column is time vector in seconds so it starts from 0, and second column of the data).
I have tried a MATLAB function block but whenever I tried to load my dataset into the function block, there always seem to be some sort of an index error where I cannot access the 2nd column of my data, and somehow my data becomes a 1x1. Are there any solutions? Due to the fact that it's a pre-made model there are way too many intricacies which kind of hinder my progress so any form of help is appreciated!
