Controllability and Observability Energies of Nonlinear<br />
Systems in RKHSes<br />
• Similarly, letting x now denote the collection of m = Np observability<br />
samples, we can approximate the future output energy by<br />
ˆLo(x) = 1<br />

where ko(x) := ( K(x, dµ) ) Np<br />
is the Np-dimensional column vector<br />
µ=1<br />
containing the kernel products between x and the observability samples.<br />
