Robust H/sub /spl infin// FIR filtering for uncertain time-varying nonlinear systems

摘要

Investigates the robust nonlinear H/sub /spl infin// filter with FIR (finite impulse response) structure for nonlinear discrete time-varying uncertain systems represented by the state-space model having parameter uncertainty. Firstly, the discrete-time nonlinear H/sub /spl infin// FIR filter without parameter uncertainty is derived by using the equivalence relationship between the FIR filter and the recursive filter, which corresponds to the standard nonlinear H/sub /spl infin// filter. Secondly, the robust H/sub /spl infin// FIR filter is proposed for discrete-time nonlinear uncertain systems. It is also derived from the equivalence relationship between the robust nonlinear H/sub /spl infin// FIR filter and the robust nonlinear H/sub /spl infin// filter proposed by de Souza et al. (1993).
