变截面涡轮增压器控制系统仿真研究

Computer simulation development of VGT electronic control turbochargering technology

电控变截面涡轮增压系统,可充分利用柴油机的废气能量,克服常规增压存在的低速扭矩不足、瞬态响应迟缓等问题,能在不改变高转速性能的同时,改善低速性能。以涡轮增压柴油机为研究对象,在MATLAB/SIMULINK仿真环境下建立电控可变喷嘴涡轮增压柴油机的动力学模型,对电控变截面涡轮增压柴油机的低速性能、控制方法进行研究。

The Variable Geometry Turbocharger Electronic control System may take full advantage of the exhaust gas energy of Diesel Engine and get over the problem in general gained press which is in short of wrest rules in the time of low speed and the transient response remains slow. The diesel engine of Turbocharger is the object of research. We set up the dynamic model of the Variable Geometry Turbocharger Electronic control diesel engine in MATLAB and study its capability of low speed and the means of control.
