If the V is positive definite, for the system to be asymptotically stable, Q should be negative definite.
A. Krasovskii’s method
B. Variable gradient method
C. Constant method
D. Non-variable gradient method
Answer:A
If the V is positive definite, for the system to be asymptotically stable, Q should be negative definite.
A. Krasovskii’s method B. Variable gradient method C. Constant method D. Non-variable gradient method
Explanation: If the V is positive definite, for the system to be asymptotically stable, Q should be negative definite. For Krasovskii’s method and in addition V should tend to infinity and the system is asymptotically stable in-the large.
