| 摘 要： | 介绍了液压挖掘机电子监控系统的组成，给出了基于CANOpen协议的数据通讯子系统的实现方法，在发动机—变量泵的功率匹配策略中，根据液压系统非线性、滞后性强、外部负载时变的特点，提出了将基于T—S模型的模糊PID控制算法，并将其应用到发动机—变量泵的复合控制中，最后通过实验验证了整个系统的可靠性和有效性。

| Abstract: | The structure of hydraulic excavators electronic monitoring-control system was introduced, and the reahzation way of data communication sub-system was described. In the power matching strategy, a fuzzy PID control arithmetic based on T-S model was proposed according to the feature of hydraulic systems which is nonlinear, big long-time delay and various loads, finally, the reliability and validity of the control system was testified by experiment. |
