| 摘 要： | 液压机械无级传动仿真模型含有非线性换段过程,模型实时求解困难,致使传统控制器硬件在环仿真难以实现。该文提出基于同步信号的控制器硬件在环仿真方法,定义了基于同步信号的硬件在环仿真时钟、同步信号周期,分析了基于同步信号的控制器硬件在环仿真时序误差,建立了基于同步信号的液压机械无级传动控制器硬件在环仿真系统,两段液压机械无级传动控制器硬件在环仿真试验表明,发动机节气门变化时,采用相同控制策略的在环控制器与控制器模型的控制效果基本一致。

| Abstract: | The model of hydraulic mechanical variable transmission(HMT) is very difficult to solve the real-time because of complication including nonlinear changeover process, so it is impossible to realize controller hardware-in -loop(HIL) in real time. Controller HIL based on sync signal was proposed, the clock of the controller HIL based on sync signal and the sync signal period were defined and subsequently time sequence error of controller HIL based on sync signal was analyzed. The controller HIL simulation system of HMT was established based on controller HIL using sync signal. The simulation results of the two stages of HMT demonstrated that the control effect of the controller hardware-in-loop was approximately the same as controller model using same control strategy when the engine throttle changed. |
