Evaluation of transient response specifications of second order control system using Scilab

Abstract: The second-order system is the lowest-order system capable of an oscillatory response to a step input. The response depends on whether it is an overdamped, critically damped, or underdamped second order system. Here we will find out transient response specifications of second order system. This system can be implemented using MATLAB software. But MATLAB software requires licence. In this paper, second order system is implemented using Scilab software. Scilab is an open source software and therefore the responses of second order system is implemented using Scilab.
