贴面压机保压系统模糊自适应PID控制与仿真研究

Fuzzy Adaptive PID Control and Simulation for Veneer Press Packing System

基于短周期贴面压机液压伺服系统动力单元的保压压力控制，分析建立了由液压缸驱动的动力单元数学模型，以该模型为控制对象，设计了模糊自适应PID控制器，并对控制系统进行了仿真研究。结果表明，所设计的模糊自适应PID较常规PID调整时间短，稳态性能好，降低了控制器的输出能耗。将模糊自适应PID控制方法应用于短周期贴面压机保压控制，是可行有效的。

Based on pressure-keeping control of the short-cycle veneer press hydraulic servo power unit,the power unit mathematical model driven by a hydraulic cylinder was established, and a Fuzzy Adaptive PID controller was designed.The simulation study results of control system showed that the response speed of Fuzzy Adaptive PID controller is faster, the adjustment time is shorter, steady-state performance is better than conventional PID controller.The new design scheme reduces power consumption of the controller output.Fuzzy Adaptive PID control method used in veneer dwell control is feasible and effective.
