edge

I'm sorry . My system has changed and now I try to be more precise. y(k+1) = a*y(k)*(n(k))/L + b*u(k+1); Where y(k) is th output of my system, n(k) is an input, u(k) too. Best Regards

Hi all, I'm a new user , I'm Italian so sorry for my bad english. My problem is that : I have this second order system non linear: [latex]x(k+1) = a \cdot x(k) + b \cdot \sqrt{(x(k-1))} + c \cdot u(k)[/latex] I would like to have a new system that is the linearizazion of my one. I know how to linearize a first order system, but in this case how can i do ? Thanks
