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。
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.
