Hello, everyone(adsbygoogle = window.adsbygoogle || []).push({});

There is a control theory problem that i would like to ask for help here.

Suppose a very simple nonlinear system as follows

x' = u

y = (2-cosx)*(2-cosx)

how to find a control law u that makes the output y can track a constant asymptotically,

of course the x should be stable too.

best wishes
