I am having trouble to define in matlab the transfer function of the following block diagram.
Gc represents the controller which produces a signal Fs,
G11 is in series with Gc.
So they may be combined to:
Based on superposition principal I can assume that the disturbance signal z0*G12 is zero. Thus I may find the transfer function of the closed loop path. That is:
How can I find the transfer function of the system by also take into account the disturbance z0*G12?
