Application of Series- Excited Motor Modeling in Nonlinear System Teaching
Peng Yi-x · 2014
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
