Question

Controllability and observability in control systems

Answer 1

Hi There,
Controllability A system with internal state vector x is called controllable if and only if the system states can be changed by changing the system input.ReachabilityA particular state x1 is called reachable if there exists an input that transfers the state of the system from the initial state x0 to x1 in some finite time interval,,

Answer 2

In the world of control engineering, there are a slew of systems available that need to be controlled. The task of a control engineer is to design controller and compensator units to interact with these pre-existing systems. However, some systems simply cannot be controlled (or, more often, cannot be controlled in specific ways). The concept of controllability refers to the ability of a controller to arbitrarily alter the functionality of the system plant.
