先导式比例流量阀控制系统的建模和仿真

Modeling and Simulation about Pneumatic Pressure Control System Based on Proportional Flow Valve of Priority

对M arrota阀的工作原理进行研究,根据其工作原理,加入了控制部分并建立了数学模型。在此基础上应用M atlab的S imu link模块进行控制系统的仿真。并通过对仿真结果的分析研究来验证数学模型的正确性,为引入更为复杂的控制算法打下基础。

On the basis of previous research of principle of Marrota valve, according to its working principle, the control part was supplemented and a model of pneumatic control system was established, the control system was simulated using Matlab and Simulink. The result of simulation validates the model of this system. The conclusion is foundation for more complicated controling arithmetic.
