Variable Structue Control to Nonlinear Systems
-
摘要: 本文研究了一般非线性系统的变结构控制.将系统变换为正则型,并引入趋近律这一新 概念,保证动态过程品质,减弱抖振.对控制作用受限情况及系统受到摄动时的鲁棒性也进行 了研究.仿真支持本文结果的有效性.Abstract: The variable structure control (VSC) to general nonlinear systems is studied in this paper. The system is first transformed into the canonical form. A new concept called the approaching law is introduced to ensure quality of the dynamical process and to alleviate the chattering. Constraints on the control activity and robustness to perturbations on the system are also considered. Simulation which supports the results is presented.
