Abstract

This paper deals with servo control for nonlinear systems approximated by piecewise bilinear (PB) models. The approximated model is found to be fully parametric. The input-output (I/O) feedback linearization is applied to stabilize PB control systems. This paper proposes two methods to design servo controllers for nonlinear systems with PB models based on I/O linearization. One is a two-degree of freedom controller and the other is a model following controller. Illustrative examples are given to show the validity of the proposed method, where a controller is represented as a Look-Up-Table (LUT).
