I have implemented utkin observer for drum boiler turbine system...The estimated state converge to actual state at a different initial condition but it is not converging at arbitraty intial condition..can someone knows the reason?
Dear Aqeel,
I suggest you to see links and attached files on topic.

Dear Aqeel ur Rahman
you can search on Sliding mode conrol technique ..that may solve the problem of convergence criteria
you can use the reaching law as $s(k+1)=d(k)$ instead of $s(k+1)=0$ where $d(k)\leq d_m$ assuming the bound of $d(k)$ is known.
