共轨式柴油发动机的轨压PID控制仿真

Common-rail Diesel Engine Rail Pressure PID Control Simulation

在高压共轨系统中,对共轨压力的控制是提高内燃机性能的关键,针对被控对象的特点,建立了被控对象的仿真模型。采用PID控制算法实现了对共轨压力的闭环控制,利用MATLAB/SIMULINK对系统进行了仿真,为实现神经网络模糊PID控制算法在轨压控制中的应用打下了良好的基础。

In the high-pressure common rail system, the common rail pressure control is the key to improve the performance of internal combustion engines, for the characteristics of the controlled object, the establishment of a simulation model of the controlled object. The PID control algorithm to achieve closed-loop control of the common rail pressure, use of MATLAB / SIMULINK of the system was simulated, and laid a good foundation for the application of neural network fuzzy PID control algorithm in the control of rail pressure.
