state variable

1. A device (or a computer program) that estimates or observes the state variables
3. particular state variables which are obtained from one of the system variable and its derivatives.
4. a control system design technique ,in which the state variables are used for feedback to achieve the desired closed loop poles.
10. (nx1)column matrix (or vector)whose elements are state variables of the system,(where n is the order of the system).
11. 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 ).
12. modern approach for design and analysis of dynamic system.
14. The Pictorial representation of the state model of the system

2. the ratio of laplace transform of output to laplace transform of input.
5. if every state X(t) can be completely identified by measurements of the output Y(t)over a finite time interval.
6. If the system matrix, A is in the form of diagonal matrix then the state model is called ..............
7. The process of converting the system matrix A in to a diagonal matrix by a similarity transformation using the modal matrix M
8. the condition of a system at any time instant, t.
9. x = Ax + Bu, y = Cx + Du
13. 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.
