I'm trying to model an actuator in Simulink based transfer functions previously derived.
One of functions is $$\omega_p=G_2(K_cG_1V_c-c)$$ where $$G_1=\frac{K_e}{\tau_es+1}$$ $$G_2=\frac{1}{c+K_cK_wG_1}$$
where $K_c,K_w,K_e,c,\tau$ are constants. I'm not really sure what it means to have a transfer function inside another and how to model it. We tried substituting $G_1$ into $G_2$ directly but the result didn't seem right. Would really appreciate if someone could explain what it means, how to model it in Simulink or point me in the right direction.
Thanks in advance.
Update: The other part of our system seemed to have been the one causing problems instead of the transfer functions it turned out.
