Web10 de abr. de 2024 · In addition, in contrast to the expectation y ∗, the variance matrix Q y ^ depends on the strength of the noise. Here, the trace of the matrix Q y ^ is the H 2 norm of the linear system where w (t) is seen as an input to the system. This H 2 norm is often used to analyze the fluctuations of the system subjected to disturbances. 13–15 13. B. K.
