Controllability and Observability.

Controllability and Observability. Controllability and observability are two very important things related to state space analysis. There are many tests for checking controllability and obervability and these tests are very essential during the design of a control system using state space approach. Controllability. Controllability verifies whether is state variable is useful or not. It checks whether a state variable can be manipulated for obtaining the required output. If a state variable is not controllable then there is no meaning in selecting it for any operation. If a particular state variable is found uncontrollable , then it is left untouched and…

State space analysis

State space analysis. State space analysis is an excellent method for the design and analysis of control systems. The conventional and old method for the design and analysis of control systems is the transfer function method. The transfer function method for design and analysis had many drawbacks. Drawbacks of transfer function analysis. Transfer function is defined under zero initial conditions. Transfer function approach can be applied only to linear time invariant systems. It does not give any idea about the internal state of the system. It cannot be applied to multiple input multiple output systems. It is comparatively difficult to…
