本文针对液压大系统仿真与辨识的需要,提出并发展了一种性能参数建模法。该法使液压系统的数学模型建立在液压元件数学子模型的基础之上,根据拓扑结构在元件结点上建立系统模型相应的方程。与以往传统的显式状态空间表达式不同,该法采用隐式状态空间表达式。通过计算机仿真证明这种方法通用性强,运算速度快并开辟了静动态仿真合一的途径。从应用的角度看,该法面向用户,适用于大系统仿真。
In this paper, according to the need of hydraulic large-scale system simulation and identification, a performance parameter modeling method is proposed and developed. The method makes the mathematical model of hydraulic system based on the mathematical sub-model of hydraulic components, and establishes the corresponding equations of the system model on the component nodes according to the topology. Different from the traditional traditional explicit state space expression, this method uses implicit state space expression. Computer simulation shows that the method is universal, fast and opens up the way of static and dynamic simulation. From the application point of view, this method is for users and is suitable for large system simulation.
