Lastly , experimentations are carried out on chaochai 6102bq engine and the data of the thermal parameters according to different oil - apply lead angle is derived . the influence of the change of oil - apply lead angle on the rate of heat release is researched , then a reference is provided for building an accurate heat release model
最后，在朝柴6102bq柴油机台架上进行了试验，对不同供油提前角下柴油机的热工参数进行实机测试，对试验结果进行了处理、分析，研究了供油提前角的改变对放热规律的影响，为建立该故障下的燃烧放热模型提供参考。
The modulating signals of firing delay angle at the rectifier and firing lead angle at the inverter , and the excitation voltage are chosen to be control variables . the offset of the current of dc line and the extinction angle and the power angle of generator are chosen to be control outputs . then a nonlinear controller is designed for the system under study according to direct feedback linearization theory
以整流侧触发延迟角的调节信号、逆变侧触发超前角的调节信号以及发电机励磁电压作为控制变量,以直流线路电流、逆变侧关断角以及发电机功角的偏移量作为目标输出,用直接反馈线性化方法设计了系统的非线性控制器。
