state variable

4. each of a set of values of a parameter for which a differential equation has a non-zero solution (an eigen function) under given conditions.
5. If the system matrix, A is in the form of diagonal matrix then the state model is called ..............
9. A device (or a computer program) that estimates or observes the state variables
10. (nx1)column matrix (or vector)whose elements are state variables of the system,(where n is the order of the system).
11. particular state variables which are obtained from one of the system variable and its derivatives.
12. x = Ax + Bu, y = Cx + Du
13. if it is possible to transfer the system state from any initial state X( t0)at any other desired state X(t),in specified finite time by a control vector U( t ).
14. The process of converting the system matrix A in to a diagonal matrix by a similarity transformation using the modal matrix M

1. The Pictorial representation of the state model of the system
2. a control system design technique ,in which the state variables are used for feedback to achieve the desired closed loop poles.
3. the condition of a system at any time instant, t.
6. if every state X(t) can be completely identified by measurements of the output Y(t)over a finite time interval.
7. modern approach for design and analysis of dynamic system.
8. the ratio of laplace transform of output to laplace transform of input.
