摘要
采用线圈电流作为控制信号建立开关电磁阀精确数学模型,通过线控液压制动系统增压阀的保压试验验证开关电磁阀数学模型的正确性。采用MATLAB/Simulink软件仿真分析不同线圈电流下开关电磁阀的4种工作状态,提出"流量可控因子"的概念用于综合评价开关电磁阀的非线性流量可控性。探讨了电磁阀结构参数对其非线性流量可控性的影响效果,采用自适应权重粒子群优化算法对电磁阀非线性流量可控性进行优化,经优化后开关电磁阀流量可控性提高了119.7%。
A precise mathematical model of on-off solenoid valve is established using coil current as the control signal,and the correctness of the model is verified by experiment of keeping pressure on booster valve of the electronic hydraulic brake system.The four working states of the on-off solenoid valve under different coil currents are analyzed using MATLAB/Simulink software.The concept of"flow controllable factor"is proposed to evaluate the nonlinear flow controllability of the valve.The effect of the solenoid valve structural parameters on its nonlinear flow controllability is deeply analyzed.Adaptive weight particle swarm optimization algorithm is applied to optimize the nonlinear flow controllability of the solenoid valve.After optimization,the flow controllability of the solenoid valve is increased by 119.7%.
