In this paper estimates of the abscissa of stability for stable linear continuous systems are determined based on the value of the integral of the time-weighted quadratic performance index. Similar results are obtained for linear discrete systems using the quadratic sum and the time-weighted quadratic sum. It is shown how the use of the Schwarz matrix may simplify the results.
