摘要
本文介绍了上海磁悬浮工程专用DZY300型运梁车的转向系统设计原理与实现过程。以CAN总线为基础,来实现转角信号的实时检测和电液比例阀的远端控制;从而利用总线通讯技术,实现了大闭环控制系统。在采用经典PID控制律时,针对工程实际情况进行了改进。理论充分与实际相结合,保证调节实时性的同时,有效地解决了转向系统中出现的超调振荡、反复微调节和调节不平稳现象。
In this paper, the design principle of the DZY300 bridge transport vehicle turning system is discussed. The real - time signal acquisition from the turning sensors and electro - hydraulic proportional valve remote control is realized by using CAN field bus technology; so the whole big negative feedback control loop is setup. Meanwhile, the classic PID control law has been mended and improved closely according to project need. Thus the real time quality is guaranteed, and the problem of over shoot vibration phenomena, repeated micro - adjusting phenomena and unstable adjusting phenomena is improved completely.
