Types of Stability

There are 3 types of stability which are as follows:

  • Steady State Stability
  • Transient Stability
  • BIBO Stability

Steady State Stability

Steady-state stability means when a system is subjected to constant input for a long duration of time and the system results in a stable output, it is known as steady-state stability. When a dynamic system provides a stable output during any disturbance in the input, it is said to be a stable system.

Transient Stability

When a system changes its state, it is known as a transition. During the transition period, whether the system is stable or not when subjected to some disturbance is determined by the transient stability.

BIBO Stability

Bounded input and bounded output stability show a system is stable when the system returns the bounded output when the bounded input is given. When the output is controllable, the system is stable else it 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.

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....

Conclusion

In this article, we have studied stability in the control system. Stability is crucial for any dynamic system for proper functioning. There are various techniques from which we can determine the stability of the system which is discussed in the article. We have also studied its applications, advantages, and disadvantages for a better understanding of the concept. This sows that if the output is controlled then we can say that the system is stable or if in open loop transfer function, any two poles are present on the imaginary axis – then the system is said to be stable....
