A third order system is approximated to an equivalent second order system. The rise time of this approximated lower order system will be:
A. Same as the original system for any input
B. Smaller than the original system for any input
C. Larger than the original system for any input
D. Larger or smaller depending on the input
Answer:B
A third order system is approximated to an equivalent second order system. The rise time of this approximated lower order system will be:
A. Same as the original system for any input B. Smaller than the original system for any input C. Larger than the original system for any input D. Larger or smaller depending on the input
Explanation: As order of the system increases the system approaches more towards the ideal characteristics and if the third order system is approximated to an equivalent second order system then the rise time of this will be smaller than the original system for any input.
