摘要

Through to the second order system mathematical model and transfer function analysis,using the differential sum circuit this paper realizes a second-order system,and using MATLAB and Multisim,respectively,the two instruments on the mathematical model and the circuit simulation analysis,it validates the correctness and feasibility.The results show that using the differential sum circuit can reduce the design complexity,improve the system stability.%文中通过对二阶系统的数学模型和传输函数的分析,采用差动求和电路实现了一个二阶系统,利用MATLAB和Multisim两种工具分别对数学模型和电路进行了仿真分析,验证了正确性和可行性.结果表明,使用差动求和电路可以降低设计复杂度,提高系统稳定性.
