摘　　要：针对人造板连续平压机升降系统控制精度低,多液压油缸同步控制困难等问题。分析了多液压油缸系统常规的控制算法,设计了具有自学习和自适应能力的模糊PID控制器,以弥补传统PID控制器在控制过程中的不足。在Matlab/Simulink环境下,搭建了多液压油缸控制系统仿真模型,仿真结果表明基于传统PID改进的模糊PID控制系统,控制精度高、收敛速度快、稳定性能好,能够很好地实现多液压油缸的准确控制。Aiming at the problems of low control precision in lifting system of continuous flat press for wood-based panel and difficulty in synchronizing control of multi-hydraulic cylinder, the conventional control algorithm of multihydraulic cylinder system is analyzed in this paper. A fuzzy PID controller with self-learning and adaptive ability is designed to make up for the deficiency of the traditional PID controller in the control process. Under the environment of Matlab/Simulink, the simulation model of multi-hydraulic cylinder control system is built. The simulation results show that the improved fuzzy PID control system based on traditional PID has high control precision, fast convergence speed and good stability, which can realize the accurate control of multi-hydraulic cylinder.
