驼峰车辆减速器闭环控制PID参数的模糊自整定

摘要

编组站车辆减速器是实现车辆溜放调速控制的关键设备之一，而目前使用的过程控制数学模型调速方案存在控制精度不高等缺点。现基于模糊自整定的原理，根据驼峰车辆减速器控制系统的性能和要求，提出一种按减速器调速过程对不同溜放车组的参数自整定的方法，并设计出了模糊自整定PID控制器。经过多次试验及调整，制定适合于驼峰车辆减速器控制系统的模糊控制规则，利用模糊控制策略可实现对PID参数的最佳调整。以此可以实现驼峰车辆减速器对速度的控制。%Retarder is one of the most important equipment to achieve precise control of truck speed in marshaling yard. However, the mathematical speed control model for process control system has some shortages with low control precision. So, based on the principle of parameter fuzzy self-turning PID and the performance and requirements of retarder control system, a new control method and PID controller is designed to control different kinds of trucks at different speed levels. Moreover, the best fuzzy control rule that adapts to the hump retarder speed control system is worked out after many tests and adjustments. The fuzzy control concept can be employed to offer optimized PID parameter adjustment so that the precise control of hump truck speed can be controlled.
