What is Stability?
The stability of the system means when a controlled input is provided to any dynamic system, it must result in providing the controlled output. In other words, the system must be BIBO stable i.e., bounded input bounded output system. If the system is not in our control i.e., uncontrolled output is obtained on providing the bounded input then the system is said to be unstable.
The above image shows a Unit Step Signal which is an example of the bounded signal. When the value of time (t) on the x-axis increases, the output value remains 1. This shows that the above signal is stable.
The above image shows a Unit Ramp Signal which is an example of the un-bounded signal. When the value of time (t) on the x-axis increases, the output value increases continuously. This shows that the above signal is unstable.
Control Systems – Stability
Control systems are used to control the behavior of any dynamic system. It provides accurate information about the dynamic system so that it can work well. One of the important aspects of the control system is STABILITY. The stability of the system is important in order to get the desired output from the system. In this article, we will deal with how control system analysis helps in providing stability to the system. We will also study types of stability, applications, and many more.
