非线性系统设计性实验教学研究

Teaching Research on Design-based Experiment of Nonlinear System

为了让学生能够对非线性系统有充分地了解,实验教学是必不可少的环节与手段。采用层层递进的方式,以Lorenz系统的电路设计为例阐述了设计性实验的实现过程,全方位考察学生的科研能力。基于已有的数学模型,通过理论分析与软件仿真相结合的方法得到符合实际要求的Lorenz电路设计模型,采用理论指导实践的思维方式,制作硬件实验电路验证电路设计模型的有效性。通过软硬件相结合的方式引导学生进一步理解非线性系统,培养实践创新能力,提高科学素养。

To help students fully understand the nonlinear system, experiment teaching is an essential link and method. This paper adopts a progressive approach, taking the circuit design of the Lorenz system as an example, to illustrate the implementation progress of the design-based experiment, and examine the scientific research ability of students in an all-round way. Based on the existing mathematical model, a Lorenz circuit design model that meets the actual requirements is obtained through a combination of theoretical analysis and software simulation. Adopting the thinking mode of theory guiding practice, the validity of the circuit design model is verified by making a hardware experiment circuit. The software and hardware are combined to guide students to further understand the nonlinear system, cultivate their practical and innovative ability, and improve their scientific literacy.
