【摘要】：針對自動控制原理中的典型二階系統(tǒng),以串聯(lián)RLC電路為研究對象,建立了RLC電路系統(tǒng)的微分方程、傳遞函數(shù)、動態(tài)結(jié)構(gòu)圖以及系統(tǒng)狀態(tài)空間方程,利用現(xiàn)代控制理論分析了系統(tǒng)的能控、能觀性;介紹了阻抗法建立RLC系統(tǒng)的動態(tài)數(shù)學(xué)模型,并利用Matlab中的Simulink建立了系統(tǒng)動態(tài)仿真模型,同時進(jìn)行了單位階躍響應(yīng)與單位斜坡的響應(yīng)的分析與研究,進(jìn)一步充實了實驗教學(xué)內(nèi)容,便于實現(xiàn)理論與仿真實驗的有機(jī)結(jié)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.
