非线性系统相轨迹教学仿真平台设计

Design the Teaching Simulation Platform of the Phase Locus of the Non-linear System

针对授课过程和教学实验中绘制相轨迹出现的复杂、不准确和不直观的问题,该文利用Simulink和GUI设计开发了非线性系统相轨迹的教学仿真平台。在该平台上,可调取由Simulink构建的非线性系统仿真模型,并且可交互式地设置或修改系统参数,以实现非线性系统相轨迹的绘制与分析。实践结果表明,该教学仿真平台能够解决上述问题,且交互性好,操作简单,既能丰富教学手段,又可激发学生的学习兴趣,培养学生的研究和创新能力,改善教学效果,提高教学质量。

In view of the complicated,inaccurate and nonintuitive problems of drawing the phase trajectory in the course of teaching and teaching experiments,this paper uses Simulink and graphical user interface （GUI） to design and develop a teaching simulation platform for the phase trajectory of nonlinear system.On the platform,the nonlinear system simulation model constructed by Simulink can be set up,and the system parameters can be set or modified interactively so as to realize the plotting and analysis of the phase trajectory of the nonlinear system.The practice results show that the teaching simulation platform can solve the above problems with good interaction and simple operation.It can not only enrich teaching methods,but also stimulate students interest in study,cultivate students research and innovation ability,improve teaching effect and improve teaching quality.
