【摘要】：针对自动控制原理中的典型二阶系统,以串联RLC电路为研究对象,建立了RLC电路系统的微分方程、传递函数、动态结构图以及系统状态空间方程,利用现代控制理论分析了系统的能控、能观性;介绍了阻抗法建立RLC系统的动态数学模型,并利用Matlab中的Simulink建立了系统动态仿真模型,同时进行了单位阶跃响应与单位斜坡的响应的分析与研究,进一步充实了实验教学内容,便于实现理论与仿真实验的有机结合。
[Abstract]:Aiming at the typical second-order system in the principle of automatic control, the differential equation, transfer function, dynamic structure diagram and state space equation of the RLC circuit system are established with series RLC circuit as the research object. The controllability and observability of the system are analyzed by using modern control theory, the dynamic mathematical model of RLC system is established by impedance method, and the dynamic simulation model of system is established by using Simulink in Matlab. At the same time, the unit step response and the unit slope response are analyzed and studied, which further enriches the experimental teaching content and facilitates the organic combination of theory and simulation experiment.
