First of all, I used Fast v8 linearization to derive 15 seperate .lin file. Secondly, using GetMats_f8 averaged them and then applied mbc.m.
obtaining MBC_AvgA, MBC_AvgB, MBC_AvgC, MBC_AvgD as the state-space matrices, I constructed the ss model. and then cropped the model such that it has only 3 inputs(horizontal wind speed, generator torque, comulative blade pitch).
The FAST v8 input files which were used to obtain such model are as follows:
