基于MATLAB的RLC阻尼振荡电路仿真分析

Simulation Analysis of RLC Damping-Oscillatory Circuits Based on MATLAB

在电路分析中经常会遇到一些阻尼振荡电路,由于这类电路在高压断路器开断能力测试、受控热核研究等许多重要的工程领域有着广泛的应用,因此有必要对此类电路的特性加以研究。本文首先介绍了建立数学模型的方法,然后利用了时域中传统的微分方程法和频域中经典的拉普拉斯变换法对电路进行分析。最后借助于MATLAB软件来对两类RLC电路的过渡过程进行仿真分析,并对其产生的错误作出了解释,此外还给出了一种解决的方法。

Damping - oscillatory circuits are often encountered in the fields of circuit analysis. It is necessary to discuss and deliberate this type of circuit because they are widely used in many important fields of engineering, such as the switch test of high - voltage circuit - breaker, the research of controllable thermonuclear reaction, etc. First the paper introduces how to establish the maths model and then presents the methods of traditional differential equation in time domain and classical Laplace transformation in At last the article provides a transient simulation to two kinds of RLC circuits supported by MATLAB and explains why the error can produce, in addition, it also provides a correct way to solve the problem.
