A stock-flow system models the level of water in a lake. Near a certain equilibrium point, there are three feedback loops: an amplifying feedback loop with strength of +0.55 per month, a stabilizing feedback loop with strength of -0.09 per month, and an amplifying feedback loop with strength of +0.79 per month.
Calculate the strength of the overall feedback.
One of the disadvantage of negative feedback loop is lag caused because it can only be exerted after controlled variable has been disturbed. In order to minimize lag between a change in a controlled variable and the action of the effector, it is advantageous for the body to anticipate any likely change. Which one of the following physiological mechanism achieves this?
Select one:
a. Feedbackward control
b. Feedforward control
c.Positive feedback control
d. All of the above
e. None of the above
For a unity negative feedback control system having an open-loop transfer function, G(s) as given
