摘要
以采煤机电液比例阀控缸位置控制系统为研究对象,建立了电液比例阀控缸位置控制系统的数学模型,利用单神经元与PID相互结合的控制方法,在simulink中设计单神经元的采煤机电液比例阀控缸位置控制系统自适应PID控制器,在有负载扰动下进行仿真,并对突变负载扰动时常规PID控制和基于单神经元PID控制进行阶跃响应对比。仿真结果显示单神经元自适应PID控制器比常规PID控制系统具有较强的鲁棒性、自适应性,对采煤机电液比例调高控制能够达到自适应控制。
Based on the position control system of electro-hydraulic proportional valve control cylinder,the mathematic model of electro-hydraulic proportional valve control system is established. Using single neuron and PID control method,a single neuron-controlled hydraulic proportional valve control cylinder position Control System Adaptive PID controller is designed in Simulink. The simulation is carried out under the load disturbance,and the step response is compared with the conventional PID control and the single neuron PID control for abrupt load disturbance. The simulation results show that the single neuron adaptive PID controller has stronger robustness and adaptability than the conventional PID control system,and can achieve adaptive control for the proportional control of the electro-hydraulic ratio of coal mining.
