基于模糊PID的双注浆泵同步系统的仿真与研究

Simulation and Research on Synchronization System of Double Grouting Pump Based on Fuzzy-PID

针对传统双注浆泵同步系统中同步精度难以保证的问题,提出了基于模糊PID控制的双注浆泵同步系统。利用电液比例阀控制液压缸,液压缸活塞杆直接控制注浆泵活塞,因此,可以通过控制液压缸活塞杆位移,保证注浆泵活塞位移同步,从而使双注浆泵的进料与出料过程同步。采用AMESim/Simulink对该系统进行联合仿真,并进行了实验验证,与传统无模糊PID控制该系统的结果对比,结果表明,模糊PID控制可以有效改善同步注浆系统的控制精度。

Aiming at solving the problem that the controlling accuracy of the traditional synchronization system of double grouting pump is difficult to be guaranteed,a synchronization system of double grouting pump based on fuzzy PID is proposed.The electro-hydraulic proportional valve is used to control the hydraulic cylinder.The piston rod of hydraulic cylinder directly controls the grouting pump’s piston.Therefore,the piston displacement of the grouting pump can be synchronized by controlling the displacement of the piston rod of the hydraulic cylinder,so that the feed and discharge of double grouting pump are synchronous.The system is simulated by AMESim and Simulink,and verified by experiments to compare with the traditional system.The results show that the fuzzy PID controller can effectively improve the precision of the system.
