【摘要】 针对斩波式串级调速系统模型的不确定和系统强非线性的特点以及传统转速电流双闭环PI控制方法的缺点, 提出了一种无源控制方法。在系统等效电路的基础上,建立了系统的Euler-Lagrange模型,并根据该模型推导出其无源控制策略。最后利用Matlab／Simulink对系统进行仿真验证,结果表明无源控制方法控制下系统有较好的动态和稳态性能。更多还原

【Abstract】 Aiming at boost chopper type slip energy recovery system’s indeterminate model and strong nonlinear character, also the disadvantage of the traditional control scheme, passivity - based control scheme is applied to solve these problems. The Equivalent circuits is firstly established and then the Euler - Lagrange model. The passivity - based control scheme is deduced by using this Ruler - Lagrange model. Matlab/Simulink is used to simulate the system and good result is shown.更多还原
