从石油钻机传动系统负载特性出发,提出了ARM+DSP+FPGA为主要控制系统的系统架构,对变频器主电路结构、异步电机矢量控制原理、间接矢量定向控制架构、主/从控制方案进行了分析说明。经过石油现场应用,证明了该控制系统具有良好的动态响应性能和控制性能。
Based on the load characteristics of oil rig drive system, the system architecture of ARM + DSP + FPGA is proposed as the main control system. The main circuit structure of inverter, the vector control principle of induction motor, the structure of indirect vector control and the master / slave control scheme Analysis and explanation. After oil field application, the control system has been proved to have good dynamic response and control performance.
