单片机实现比例减压调速复合控制原理

Compound control principle of proportional pressure reduction and flow regulation with single chip computer

作者应用８０９８单片机的数学运算功能，提出通过检测阀口压差与阀开度并对压力与流量非线性关系实时校正来控制流量的方法，克服了动态流量不易检测的难点，仅用一比例节流阀就可实现减压与调速的复合控制，用于实际可简化油路，降低系统成本。

Anew principle was put forward to control pressure and flow compoundly through detecting differential pressure and displacement of valve and nonlinear correcting with single chip computer.With this method ,the proportional throttle valve can have pressure reducing and flow regulating multi-funtion.If used in practice,it can simplify hydraulic circuit and reduce system cost.
