摘 要:现代化工厂的生产流水线大多依靠异步电机进行电力传动,而电机调速的准确程度、响应时间等参数对产品质量与工作效率有着重要影响。针对大型流水线需求,采用空间矢量脉宽调制技术(Space Vector Pulse Width Modulation,SVPWM),研究流水线调速系统的控制电路。在Simulink环境下构建变频调速系统的仿真模型并合理设置参数,通过仿真验证系统性能,结果表明:采用SVPWM的流水线调速系统,利用电流内环、转速外环的PI控制方式,可实现在0~1600 r/min范围内的转速可调,响应时间小于30 ms的大型流水线变频调速系统。系统具有调速准确度高、响应时间短等优点,满足现代化工业流水线的需求。The production lines of modern factories mostly rely on asynchronous motors for power transmission,but the accuracy of motor speed regulation,response time and other parameters have an important impact on product quality and work efficiency.In view of the demand of large-scale assembly line,the control circuit of assembly line speed regulation system is studied by using space vector pulse width modulation(SVPWM).The simulation model of frequency conversion speed regulation system is constructed in the Simulink environment and the parameters are set reasonably.The performance of the system is verified by simulation.The results show that the assembly line speed regulation system using SVPWM,using the PI control mode of current inner loop and speed outer loop,can realize the speed adjustment in the range of 0~1600 r/min,and the response time of large-scale assembly line frequency conversion speed regulation system is less than 30 ms.The system has the advantages of high speed accuracy and short response time,which meets the demand of modern industrial assembly line.
