摘要
为满足车用柴油机日益严格的排放法规和更高燃油经济性、动力性的要求,需要优化和控制电控柴油机的运转参数。设计了以DSP56F807为核心的电磁执行器控制系统,通过对柴油机电磁执行器的分析,建立了电磁执行器的数学模型,用阶跃响应法确定了电磁执行器的传递函数,提出了基于遗传算法的PID整定方法,试验结果表明:此方法能取得令人满意的控制效果,可以成功地应用于柴油机的台架试验中。
In order to satisfy the demand of increasingly stringent emission regulations and higher fuel economy and dynamic performance of vehicle diesel engines, the running parameters of electronic control diesel engines were optimized and controlled. The diesel electromagnetic actuator control system was designed based on DSP56F807. The mathematic model of electromagnetic actuators was developed by using analysis of diesel electromagnetic actuators. The transfer function of electromagnetic actuator was confirmed by the use of step signal response method. The PID regulated method based on genetic algorithm was presented. Experimental results prove that this control method can obtain quite a good control effect and use in the test bench of diesel engine successfully.
