A controlled process is shown in block diagram form.

A block diagram of a feedback control system. An input feed r, goes into a summing junction where it is added to a negative feedback signal from G of n. The output of this summing junction goes to a controller block G of c, producing signal u. This signal u then goes to block G of p. Input d passes through block G of d and is added to the output of G of p at another summing junction. The output of this summing junction goes to a measurement block G of m, producing the final output y. A feedback loop from y passes through block G of n and returns to the first summing junction.

What is the closed-loop transfer function describing the effect of d and r on y?
