In this literature, a new nonlinear digital controller is proposed for analyses and designs of sampleddata feedback control systems. The controller is derived from the converging characteristic of a specified numerical series. The ratios of neighbourhoods of the series are formulated as a function of the output of the plant and the reference input command, and will be converged to be unities after the output has tracked the reference input command. Limitation of the series can be applied to get better performance. Two kinds of servo system, a time-delay system, one very high order system and a 2×2 multivariable aircraft gas turbine engine are used to illustrate effectiveness of the proposed nonlinear digital controller. Comparisons with other conventional methods are also made.
