摘　　要：为解决长纤维抗裂复合封层机在作业过程中出现的撒(洒)布不均匀问题,提出了一种模糊分数PID协同控制方法,采用分数阶PID控制器,实现了长纤维抗裂复合封层机行走与撒布系统的协同控制。结合模糊控制规则,对分数阶PID参数进行了在线实时优化,提升了系统的整体控制性能。通过Simulink仿真实验,对比了该方法与传统PID控制器的综合性能。结果表明:所提控制器在行走和撒布过程中的响应速度、超调量及稳态误差等方面均显著优于传统PID控制器;并通过实车试验平台,对所提控制方法进行了试验验证,成功实现了长纤维抗裂复合封层机行走过程中纤维、沥青、碎石的协同控制,为长纤维抗裂复合封层机的行走与撒(洒)布系统协同控制领域提供了新的研究思路。To solve the problem of uneven spreading ratio in the traditional control method of long fiber anti-cracking composite sealer during walking,a fuzzy fractional PID cooperative control method is proposed.The method employs a fractional-order PID controller to realize cooperative control of the travelling and spreading mechanism within the long fiber anti-cracking composite sealer.By integrating fuzzy control rules,the parameters of the fractional-order PID controller are dynamically optimized in real-time,thereby enhancing the overall control efficacy of the system.The performance of the proposed method is compared with that of the traditional PID controller through Simulink simulation experiments,and the results show that the proposed controller has significant superiority in terms of the response speed of traveling and spreading as well as the steady-state error.The proposed control method has been verified through the real vehicle test bed,and the synergistic control of fibre,asphalt and gravel during the travelling process of the long fibre anti-cracking composite sealer has been successfully achieved,which provides a new research idea in the field of synergistic control of travelling and spreading system of the long fibre anti-cracking composite sealer.
