液压机械无级传动的自动控制研究

A Study on the Automatic Control of Hydro-Mechanical Variable Transmission

为了探索液压机械无级传动实现自动控制的可行性 ,建立了液压机械无级变速器的单参数刚性控制结构的模型 ,研制了液压机械无级传动自动控制器及相应的控制软件 ,通过台架试验验证了控制单元采用增量式 PID控制算法的可行性 ,并获得了一套可行的 PID控制整定参数 。

To determine the feasibility of automatic control of hydro mechanical variable transmissions, a single parameter rigid automatic control model of hydro mechanical variable transmissions was established. The ECU and relevant control software were developed. In prototype testing, PID control logic has been used and ideal control parameters obtained. Prototype of the hydro mechanical variable transmission has been controlled automatically by ECU in testing.
