摘要：

为了缩短共轨压力控制算法的开发周期及降低开发成本,通过Matlab/Simulink及RTW Embedded Coder工具箱完成前馈控制加比例积分微分（PID）反馈控制的高压共轨压力控制策略的建模及自动代码生成.针对共轨压力在发动机一个工作循环内的波动规律,共轨压力控制系统定相位采样共轨压力传感器,提高共轨压力控制的稳定性.试验结果表明,稳态时共轨压力波动幅度小于1.5 MPa,阶跃响应时共轨压力超调量在2 MPa以内,稳定时间小于0.5 s,在不同燃油喷射量下,轨压波动总能稳定在±1.5 MPa以内.该控制策略易于实现,并兼顾控制精度及响应速度,完全满足高压共轨压力控制要求.

Abstract:

In order to shorten rail pressure control strategy development cycle and reduce development costs，modeling and automatic code generation of feed forward control plus proportional-integral-differential(PID) feedback control strategy were completed through the Matlab / Simulink and RTW Embedded Coder kits. For improving the control stability, rail pressure control system was scheduled to sample rail pressure sensor on fixed phase according to the rail pressure fluctuation rules in an engine working cycle. The test results show that rail pressure steady state error is less than 1.5 MPa, maximum overshoot is about 2 MPa or less during pressure step response and settling time is less than 0.5 s, pressure fluctuation is less than ±1.5 MPa under different fuel injection quantities. The control strategy is easy to implement, control accuracy and response performance has met the requirements of common rail pressure control system.
