摘　　要：针对汽车空气动力试验测试过程中常出现的钢带位置偏移问题,设计了一套基于西门子运动控制器SIMOTION的车轮转速控制系统。采用高精度边缘检测传感器采集高速钢带的位置,通过PROFINET网络传输到控制器。SIMOTION控制器根据钢带的位置采用比例微分算法控制推杆电机驱动器的输出频率与运行时间,实现对电动推杆调节量的控制,从而完成钢带的有效纠偏。上位机通过以太网给定主电机转速,编码器采集主电机转速并由PROFINET网络反馈给SIMOTION控制器,构成转速闭环控制。测试表明:在垂直承重300kg的情况下,钢带在3000r/min的速度下能稳定运行30分钟以上。该系统在汽车设计及轮胎的测试方面有重要的参考价值。A steel belt tracking control system based on Siemens SIMOTION has been designed to deal with the belt .tracking problem which often appears in the automobile aerodynamic testing process.The sign of high speed steel position which has been detected by the high precision edge sensor transmitted through the PROFINT network.The SIMOTION controller based on the steel belt position using PD algorithm to control output frequency and running time of the pushing rod motor drives,realize the electric push rod adjustment quantity control,thus completing the effective correction strip.PC through the Ethernet given rotating speed of the main motor,encoder for collecting main motor speed and by the PRQFINET network feedback to the SlMOTION controller,constitute the closed loop speed control.
