First Order System vs. Second Order System
This results in a slower response time and less oscillation compared to a Second Order System, which has two energy storage elements and typically has two poles in its transfer function.

The ripple reduction problem was also studied by other research works. A method to reduce the up-down glitch in the frequency domain response of a fourth-order boost
A second-order system is characterized by a differential equation of second order, commonly used to model systems with two energy storage elements, such as mechanical and electrical
5.3 Second-order systems and their responses We recall from Section 2.1.2 that a second-order system is a dynamical system in which two variables are required and su!icient

Typical examples are the spring-mass-damper system and the electronic RLC circuit. Second-order systems with potential oscillatory responses require two different and independent types of energy storage, such as the inductor and the capacitor in RLC filters, or a spring and an inert mass.
Circuits with two storage elements are second-order systems, because they produce equations with second derivatives. Second-order systems are the first systems that rock back and forth in time, or oscillate. The classic example of a mechanical second-order system is a clock with a pendulum.
For this second-order system, initial conditions on both the position and velocity are required to specify the state. The response of this system to an initial displacement x(0) = x0 and initial velocity v(0) = x ̇(0) = v0 is found in a manner identical to that previously used in the first order case of Section 1.1.
A second-order circuit is characterized by a second-order differential equation. It consists of resistors and the equivalent of two energy storage elements Finding Initial and Final Values First, focus on the variables that cannot change abruptly; capacitor voltage and inductor current.
