Question: A closed-loop system is used to track the sun to obtain maximum power from a photovoltaic array. The tracking system may be represented by Figure

A closed-loop system is used to track the sun to obtain maximum power from a photovoltaic array. The tracking system may be represented by Figure 4.3 with H(s) = 1 and
G(s) = 100/тs + 1
where т = 3 seconds nominally.
(a) Calculate the sensitivity of this system for a small change in т.
(b) Calculate the time constant of the closed-loop system response.
