摘要:

讨论了电液伺服加载系统数学模型建立过程中的主要问题,结合正在使用中的一个被动式电液伺服气动力加载系统,给出了采用最小二乘法建立其数学模型的过程和结果,并从数学上证明了所建模型与被加载对象无关。

关键词: 电液伺服加载系统, 数学模型, 辨识

Abstract:

Some main problems in modelling the electro hydraulic servo loading system are discussed, and an example is given to illustrate the modelling procedure and display the results for a practical system. At the end the model has been proved not to be related to the loaded object.
