  • Abstract
    A similarity transformation that introduces zero coefficients in the A matrix of a local state-space (LSS) realization is presented. The transformation is orthogonal and thus preserves \\parallel A \\parallel . This guarantees that the number of multipliers is reduced without sacrificing zero input stability to nonlinearities satisfying |Q(x_{i})| \\leq |x_{i}| . It is shown that the transformation does not affect the sensitivity. The results are extended to the generalized asymmetric half-plane state-space model. An example of a general 1 - Q second-order filter is given.
