摘要
提出了一种改进时域采样的建模方法。在分析柴油机闭环低阶控制模型可辨识性的基础上 ,使用基于曲轴角度域的时域变周期采样和相关最小二乘算法 ,辨识了用于柴油机电子调速器参数优化的柴油机低阶动态模型。在 1 6V2 4 0 ZA和 Z61 35柴油机上的仿真和试验证明该方法简便易行 。
A new method of modeling of diesel engines is adapted based on time varying intervals.The identification of close loop low order model of control system of diesel engines is analysed.A dynamic model is established to be used in the parameter optimization of the electronic governor of diesel engines.Simulating results are compared with the test data of diesel engines of type 16V240ZA and Z6135.The advanced technique with time varying sampling intervals has been used to design the controlling systems of diesel engines.
