The input voltage applied to this circuit is $v_i$ and the voltage across the capacitor is the output voltage $v_o$. The objective is to develop a control model for controlling such systems using a control action in an optimum manner without delay or overshoot and ensuring control stability.. To do this, a controller with the requisite corrective behavior is required.

Although control theory has deep connections with classical areas of mathematics, such as the calculus of variations and the theory of differential equations , it did not become a field in its own right until the late 1950s and early 1960s. Therefore, the transfer function of LTI system is equal to the ratio of $Y(s)$ and $X(s)$.
