Unformatted text preview: s s K K s s K +-+ . There will only be a sign change in the first column if K &lt; 50 or K &gt; 580. Therefore, the closedloop system will be stable for 50 580 K-&lt; &lt; . When K = 580, the s 1 row becomes a row of zeros. The even polynomial is in the s 2 row and is 14 s 2 + 630 = 0. Solving for s , the frequency of oscillation is 6.71 rad/s....
