Question
A system is represented in state-space form as follows:
(: input, : state vector, : output)Consider the new state vector
What is the state-space representation of the system in terms of the new state vector ?
(: input, : state vector, : output)Consider the new state vector
What is the state-space representation of the system in terms of the new state vector ?
Correct answer
(C) z = bmatrix 4 & 9 \ -2 & -3 bmatrix z + bmatrix 4 \ -1 bmatrix u y = bmatrix 2 & 3 bmatrix z
Solution
Given the transformation where .
The inverse transformation is .
. Thus, .
The new state-space matrices are:
So the representation is and .
The inverse transformation is .
. Thus, .
The new state-space matrices are:
So the representation is and .
