摘要
非线性系统分析是"自动控制原理"课程中的一个重要章节,为了方便教学,利用MAT-LAB仿真工具设计了非线性系统辅助教学软件平台。该软件平台可方便地针对典型系统结构对非线性环节和线性环节进行建模,并给出相轨迹图及描述函数分析所需曲线,利用这些曲线即可进行系统稳定性分析及动态、稳态性能分析。整个软件的设计界面简单,使用方便,可大大减轻教学工作量,提高教学效果。
Nonlinear system analysis is a particular chapter in ＂Control Theory＂. The Analysis methods are very complicated and difficult to understand . The teaching analysis software of nonlinear systems, which is used to facilitate the teaching of the subject, is designed through the MATLAB simulation tools. The nonlinear and linear components in connection with the typical structure can be easily modeled through the software. The phase track diagram and the curve which the description function analysis needs can also be gotten. By using these curves, the system stability, dynamic property and steady-state errors can be analysed. The design interface of the entire software is simple and the software operates easily, which can greatly reduce the workload and improve the effectiveness of teaching.
