【摘要】 在对双缸液压电梯进行建模与仿真时 ,直接由其机理建模非常复杂 ,得不到可用于控制的数学模型 ,因此采用辨识的方法 (即实测辨识方法和机理仿真方法 )建立其模型 ,最后用MATLAB对所建模型进行了仿真比较 ,结果表明所见模型是比较合适的更多还原

【Abstract】 Because of the complexity of modeling by its mechanism in modeling and simulation of twin plurger hydraulic elevator,we can not obtain the math model which can be used in control. But we buildup the model by identification. At last we simulate the model via MATLAB and study the system’s dynamic quality. The results show that the model we build is correct.更多还原
