Abstract : This paper investigates the robust nonlinear ¥ H filter with FIR(Finite Impulse Response) structure for nonlinear discrete time-varying uncertain systems represented by the state-space model having parameter uncertainty. Firstly, when there is no parameter uncertainty in the system, the discrete-time nominal nonlinear ¥ H FIR filter is derived by using the equivalence relationship between the FIR filter and the recursive filter, which corresponds to the standard nonlinear ¥ H filter. Secondly, when the system has the parameter uncertainty, the robust nonlinear ¥ H FIR filter is proposed for the discrete-time nonlinear uncertain systems.
