I used nlgreyest to estimate parameters in my system. However, although it was able to estimate the parameter, I cannot use the compare tool to plot a graph of the estimation, as it takes too long (1hr+). Is there another way to plot the greybox model?

You might want to do it manually by accessing the details from estimation report such as parameter values, initial conditions, and fit ( https://www.mathworks.com/help/ident/ug/estimation-report.html#bup2q9z-1 ). However, I suspect the manual process would be any faster than compare()
