CAN总线在电液伺服系统中的应用研究

摘要

文中提出将CAN总线应用于电液伺服系统的状态检测和控制中.以STC89C54RD+单片机为控制核心,进行了控制节点电路设计,设计了CAN总线通讯程序,并在电液伺服系统的控制中运用了单神经元自适应PID控制.所设计的系统连接简单、通讯可靠,实时性强,易于扩展.%The application of CAN bus in status inspection and control of electro-hydraulic servo system was presented. It took STC89C54RD + as the control core,designed the circuit of control node and analyzed the program of CAN bus communication. The single neuron self-adaptive PID controller was used in electro-hydraulic servo system. The designed system is simpler to connect, betler reliable,better real-time,and easier to be expanded.
