Webimmediately and from that information determine the system stability. It is true that the Lyapunov stability test is not the right method to test the stability of linear systems when the system matrix is given by numerical entries. However, it can be used as a useful concept in theoretical considerations, e.g. to prove some other stability results. Webso the stability of the close-loop system depends on the eigenvalues of A+ BK Note that K 2Rm n has mnelements, but A + BK has only neigenvalues. So we have mndegrees of freedom (variables to freely choose) to determine neigenvalues. Looks like a favorable situation, right?

http://sysengr.engr.arizona.edu/publishedPapers/SzidarStability.pdf WebOne manner that we can determine whether the integrator is stable is by plotting the eigenvalues scaled by the timestep in the complex λ∆t plane and overlaying the stability region for the desired ODE integrator. Then, ∆t can be adjusted to attempt to bring all eigenvalues into the stability region for the desired ODE integrator. Example 1.
