Understanding the State-Space Representation
The state-space representation of a system is given by the equations:
- S(n+1) = A S(n) + B x(n)
- Y(n) = C S(n) + D x(n)
Where:
- A, B, C, D are matrices defining the system dynamics.
- S(n) is the state vector.
- x(n) is the input.
- y(n) is the output.
Transfer Function Derivation
To derive the transfer function H(z) = Y(z)/X(z), we utilize the Z-transform:
1. Z-transform of the state equation:
- Applying the Z-transform to S(n+1) leads to S(z) = A S(z) + B X(z).
- Rearranging gives: S(z)(I - AZ) = BX(z).
2. Solving for S(z):
- This can be expressed as: S(z) = (I - AZ)^(-1) B X(z).
3. Substituting into the output equation:
- The output equation in the Z-domain becomes Y(z) = C S(z) + D X(z).
- Substituting for S(z), we have Y(z) = C(I - AZ)^(-1) B X(z) + D X(z).
4. Combining terms:
- Factoring out X(z) leads to: Y(z) = [C(I - AZ)^(-1) B + D] X(z).
5. Final Transfer Function:
- Thus, we can express the transfer function as: H(z) = [C(I - AZ)^(-1) B + D].
Conclusion
The correct answer is option 'C' because it properly captures the relationship between the input and output in the Z-transform domain using the state-space representation. The final form represents the dynamics of the system effectively.
