I have completed the block diagram for the attached question, however I am having problems deriving an expression for the transfer function, in terms of parameters k1, k2, k0 and kt.© BrainMass Inc. brainmass.com March 5, 2021, 1:38 am ad1c9bdddf
So from your block diagram you have shown the output as
To = ko*I. (1)
I = e*k1. (2)
Substitute (2) in (1) to obtain
To = e*ko*k1. (3)
But you also show that the error e is given by e = VD - VM. ...
From a control loop feedback diagram the transfer function is derived for the control system
