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 以整流側觸發延遲角的調節信號、逆變側觸發超前角的調節信號以及發電機勵磁電壓作為控制變量,以直流線路電流、逆變側關斷角以及發電機功角的偏移量作為目標輸出,用直接反饋線性化方法設計了系統的非線性控制器。

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柴油機臺架上進行了試驗,對不同供油提前角下柴油機的熱工參數進行實機測試,對試驗結果進行了處理、分析,研究了供油提前角的改變對放熱規律的影響,為建立該故障下的燃燒放熱模型提供參考。
