The control to capacitor voltage transfer function as per the paper is having Iload and Vdc terms. But the transfer function i have calculated from state space approach, doesn't have both terms. Can anyone help me with this? The X matrix i.e. steady state values are correct. I have verified from both MATLAB and PSIM. The only difference lies in transfer function calculation. I want to know the effect of load perturbation. As per my analysis i am having an error in transfer function formula basically linearization. I have got the same transfer function from SFG approach. Kindly help me with the above.
Thanks in advance
