Abstract: Dynamometer of drive experimental platform features high real-time performance. A new type of dynamometer monitoring and control system for drive experiment platform is presented, which is based on a dual-network of Ethernet and Profibus-DP. A torque control model is proposed to meet the requirement of the dynamometer. Under programming environment of Delphi and SQL Server, the monitoring and control software is developed with technologies of Object Linking and Embedding(OLE) for Process Control(OPC) communication, multi-thread and ActiveX Data Objects(ADO). Experimental results show that, this monitoring and control system can run steadily, control torque accurately.
