Cooperative Control of Traveling and Spreading System of Long Fibre Anti-cracking Composite Sealer
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.
