Abstract
The lower-order suboptimal filtering method for estimating the state v ector for a special class of discrete nonlinear systems is proposed. T he dimension of state in this filter is less than that in the extended Kalman filter. The comparative less computation time required for cal culation of the filter gains and implementation of the estimation proc ess make it possible to apply this method to multidimensional dynamic systems in realtime. Examples are presented.
