(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

2. Relevant equations

Number of encirclements = Number of open loop poles - Number of Close loop poles on Right side of S plane.

3. The attempt at a solution

There is 1 open loop pole on RHS

For Close loop poles I used Routh Herwitz method and got 1 pole on RHS. 1 sign change.

So I get N = 0.

Where am I wrong?
