资料介绍

应用模拟电路实现的分段线性函数相比较数值分析而言,在速度上和参数调整上具有非常大的优势,同时分段线性函数的设计为应用等效电路模型进行非线性动力学的分析提供了基础。在分析蔡氏电路非线性电阻的基础上,针对分段线性函数的特点,结合运算放大器的线性放大和饱和特性,通过相互线性叠加,设计了几种不同特性的分段线性函数。并在MultiSiml2.0仿真软件中进行了仿真,验证了设计的正确性。设计为非线性动力学的仿真提供了一种方法,降低了仿真实验的难度,提高了计算的速度和参数调整的实时性。

As far as numerical analysis comparison is concerned, there are more advantages in the calculating time and pa- rameter adjustment of the piecewise linear function completed by analog circuit. Besides, the design of nonlinear function provides a basis for the nonlinear mechanical analysis of circuit equivalent model. Based on the analysis of Cai's nonlinear resistance circuit and characteristics of piecewise linear function, as well as operational amplifiers' linear amplification and saturability, several kinds of piecewise linear function are designed by inter linear superposition. The design is simulatedverified in the software of Multi- Siml2.0. The method provides a way for simulation of nonlinear ...
