摘要
为了提高压捆机性能和工作效率,本文针对9KG-350型牧草压捆机液压系统设计了电液比例位置控制系统。在比例方向阀上施加控制信号,通过信号控制阀开关而控制流量使活塞达到精确位置,并将模糊PID控制器引入到活塞控制性能中,对其参数及规则进一步分析。同时为验证模糊PID控制效果,使用MATLAB/Simulink平台搭建传递函数,对PID控制器和模糊PID控制器进行对比仿真研究,通过全面分析及试验证明模糊PID对于活塞的精准控制具有良好效果。
In order to improve the performance and work efficiency of the baler,an electro-hydraulic proportional position control system was designed for the hydraulic system of the 9KG-350 forage baler.A control signal was applied to the proportional directional valve,and the flow was controlled by the signal to make the piston to a precise position.The Fuzzy PID controller was introduced into the piston control performance,and its parameters and rules were further analyzed.At the same time,in order to verify the control effect of Fuzzy PID,the MATLAB/Simulink platform was used to build the transfer function,and the PID controller and the Fuzzy PID controller were compared and simulated.Through comprehensive analysis and experiments,the Fuzzy PID had good effect on the precise control of the piston.
