电液伺服系统的建模方法研究与应用

Modeling of Electrohydraulic System and Its Application

详细讨论了电液伺服系统的各种建模方法:采用机理建模法,构造了电液伺服系统的传递函数;采用模糊建模和神经网络,实现了电液伺服系统的智能建模。首先介绍了某型号武器中的自动定深电液伺服系统,提出了获取建模数据的方法,然后详述了传递函数、模糊模型和神经网络三种具体的建模算法,最后以自动定深电液伺服系统为例,构造电液伺服系统的五种模型,并对各模型进行了详细分析,为进一步实现电液伺服系统的控制奠定了基础。

Several modeling techniques were proposed to identify the electrohydraulic system：the transfer function is constructed using first-principle method,and the intelligent models are built by fuzzy modeling and neural networks.First,the automatic depth control electrohydraulic system（ADCES） of a certain type of weapon was introduced,and how to obtain the input-output data was proposed.Then,three modeling algorithms were detailed,including transfer function,fuzzy system and neural networks.Finally,five models were identified based on the ADCES;and the analysis of the obtained models lays the foundation of the controller design.
