摘要
针对直线电机/发动机系统的稳态运行特性,建立了系统数值仿真模型,并利用样机台架验证了模型的精确性。对系统稳态运行过程中的扰动因素进行了分析,针对失火、撞缸、喷油量大幅波动等极限工况,采用整个行程通过电磁力控制、上下止点加以燃烧辅助控制的方法,提出了基于动子中点速度检测与动子轨迹跟随的稳态运行综合控制策略。研究结果表明:当扰动发生后,所提出的控制策略可以在3个行程内使系统恢复稳态运行。
To investigate the characteristics of Linear Generator/Engine System,the numerical simulation model of the system was set up.The accuracy of the simulation model was validated by a prototype.The disturbance during stable operation of the system was analyzed.under the extreme conditions of misfire,knocking and large variable load,an integrated control strategy was proposed based on mid-point velocity detection and trajectory tracking.The electromagnetic force control was applied during the whole stroke,and ignition control was applied around the top dead center.Results show that the system can return to stable operation within three strokes under this control after disturbance happens.
