摘要/Abstract

摘要： 本文研究了一种新的自适应控制规律，即比例加积分控制规律和继电控制规律的综合控制。还研究了一些目前国际上自适应控制领域中没有很好解决的问题：如非线性自适应控制系统；应用滤波输入和输出以避免测量对象高阶导数问题；高阶对象和低阶模型的跟踪问题；非最小相位系统的稳定控制；利用前馈传递函数以改善系统动态特性问题。本文给出了若干数字仿真和数摸混合实时分析的结果数据和图形。

Abstract: A new adaptive controller-relay and proportional plus integral (P+I) combined controller based on Lyapunov's direct second method is derived and investigated. Some important problems encountered in the adaptive control systems is needed to solve such as nonlinear adaptive control systems; filtered input and output method to avoid the necessity of deterining the derivatives of the plant output; the transfer function of dimension difference problem between the model and the plant; combination of feedforward controller and adaptive controller; the stability of non-minimum phase adaptive control systems and appiied optimization design of adaptive controller parameters. The rear-time microprocessor application of this combined controller to the first and second order analog plants is also investigated using microcomputer IBM PC/XT and extended BASIC laugange. A generalized optimization program we developed is recommended.
