本文研究分段双线性(PB)模型逼近的非线性系统的伺服控制问题。得到的近似模型是完全参数的。采用输入输出(I/O)反馈线性化方法镇定PB控制系统。针对具有PB模型的非线性系统，提出了两种基于I/O线性化的伺服控制器设计方法。一种是两自由度控制器，另一种是模型跟随控制器。通过算例说明了该方法的有效性，其中控制器用查找表(LUT)表示。
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).
