Controllability and Observability in Control System
1. Can a system is observable but not controllable and vice versa? Comment on this.
Yes, it is possible but for the system to work efficiently, the system must be observable and controllable.
2. Has the stability been impacted due to controllability and observability?
Controllability means that the system can be controlled with different given inputs. Controlling the system on the basis of various inputs leads to stability. On the other hand, observability helps in determining the accurate information of the state which helps in providing stability to the system.
3. How is controllability determined in a control system?
Controllability is determined using a controllability matrix.
Controllability and Observability in Control System
The control system is the system that directs the input to another system and regulates its output. It helps in determining the system’s behavior. The controllability and observability help in designing the control system more effectively. Controllability is the ability to control the state of the system by applying specific input whereas observability is the ability to measure or observe the system’s state. In this article, we will study controllability and observability in detail.
