电磁阀测试系统综合控制研究

针对电磁阀测试系统中压力、流量等流体被控参数存在复杂、非线性、时变不确定性及一定程度的纯滞后等特点,提出了系统综合控制方案.以油介质电磁阀实验回路为原型,建立了系统数学模型,采用了智能控制综合算法来实现被控参数的精确控制.通过Matlab/Simulink进行了电液联合控制仿真,将仿真结果进行比较,验证了控制算法的有效性;将控制算法引用到电磁阀测试实验中,通过实验结果对比分析,最终确定了适合本系统的最优综合控制策略.

Integrated Control Study on Testing System of Solenoid Valve

In view of the features of such controlled parameters as pressure and flowrate and changeful test conditions including nonlinearity,time-varying uncertainty and certain hysteresis,an integrated control method was proposed for the testing system of solenoid valve. The mathematical models based on the testing system of the solenoid valve loop with oil as medium were developed,and the integrated intelligent control algorithm was introduced to implement the accurate control of parameters. An electro-hydraulic c...
