摘要 针对《自动控制原理》教材在阐述非线性系统小偏差线性化分析时无完整案例之不足,选取应用广泛的串励电机的线性化建模为教学案例。通过列电机的变量方程获得其动态和静态框图,围绕框图中的非线性环节作小偏差线性化处理,推导出用变量增量表示的线性化框图,指出串励电机的动态分析方法。该案例既现实又完整且相对简单,能较好地满足作为教学案例的要求。 The series-excited motor linear modeling is selected as a teaching case to make up for the lack of complete cases for explaining small deviation linearization of nonlinear system in Automatic Control Theory coursebook. The dynamic and steady state system diagram of the series-excited motor is acquired by the derivation of the variable equations, the nonlinear link of the state system diagram is handled by small deviation linearization, the linearized system diagram represented by the variable increment is deduced, and the dynamic analysis method of the series-excited motor is presented finally. The case of the series-excited motor is realistic, complete and relatively simple, and can meet the requirements as a teaching case
