Transient Response Specification
The brief response of a 2nd-order machine is characterized by using numerous key parameters:
- Rise Time (tr): The time taken for the reaction to rise from a certain low price (typically 10%) to a particular high cost (normally 90%).
- Peak Time (tp): The time taken for the response to reach its peak value.
Tp = Л /ωn √1- ζ2
- Settling Time (ts): The time required for the reaction to settle inside a precise percentage (generally five%) of its final value and continue to be there.
Ts = 4 /ζωn
- Overshoot (%OS): The maximum percentage by which the response overshoots its very last value.
%OS = e-(ζЛ √1 – ζ2) ✕ 100
- Damping Ratio (ζ): A degree of the system’s damping, influencing the charge of decay of oscillations inside the response.
Damping Ratio (ζ) = Exponential decay frequency / Natural frequency

Ts2 < Ts1 ;Tp2 < Tp1; %OS1 < %OS2.
Response of Second Order System
Control systems play a critical position in regulating and keeping the conduct of dynamic structures, making sure of balance and desired overall performance. One common form of machine encountered in the control idea is the second one-order system. The reaction of such structures is essential to understand for engineers and researchers operating in various fields. Now let’s move on to the concepts of pole and zero and the transient response to the second order system.
In contrast to the simplicity of first-order systems, second-order systems have many answers that need to be analyzed and explained. Changing first-order parameters only changes the response rate, while changing second-order parameters can change the response. For example, the second order may show similar behavior to the first order, or it may show temporary responses, either negative or weak, depending on the value of the product. In this article, we delve into the traits, analysis, and importance of the response of the second-order system on top of things theory.
