摘要

A strong comprehensive nonlinear circuit experiment is designed, and based on linear feedback controller, the chaotic synchronization control for two Chua's circuits with different motion is realized.By using the nonlinear limiting amplitude function, the synchronous control circuit diagram of Chua's circuit without inductors is designed.Its circuit structure is simple, and its operation is easy.Through adjusting the resistance value of the potentiometer, the gain of the synchronous controller is changed.In the observation of the experimental results, the asymptotic synchronization is achieved for the drive system and response system.Through the open experiment of nonlinear circuit, the students' innovative ability and scientific research ability are cultivated, and it is also helpful for the students to gain the deep learning and understanding of Nonlinear Circuit course.%设计了综合性强的非线性电路实验,基于合适的线性反馈控制器,实现运动行为不同的2个蔡氏电路系统的混沌同步控制.利用非线性限幅函数,设计等效无感蔡氏电路的同步控制电路图,电路结构简单易操作.通过调节电位器的阻值,改变同步控制器的增益,观测实验结果,驱动系统与响应系统达到渐近同步.通过非线性电路系统的开发式实验,培养了学生的创新能力和科研能力,有利于非线性电路课程的深入学习和理解.
