Condition of Controllability and Observability in S-Plane
The controllability and observability of the control system can be calculated using the transfer function. To find the same, the following points should be kept in mind:
- The transfer function represents the system in the s-plane. If the numerator and denominator polynomial do not have any common factor except constant terms, then the system is controllable.
- The same condition is applicable for the observability. There must be no pole-zero cancellation. The system cannot be completely observable in the case of incomplete input and output.
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 systemâs 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 systemâs state. In this article, we will study controllability and observability in detail.
