摘要
研究了基于曲轴角度域闭环辨识柴油机模型的建模方法. 该方法本质上属于时域辨识,在辨 识采样中应用了曲轴角度域采样原理,辨识了用于柴油机电子调速器参数调整用的低阶参数 模型. 在16V240ZA和Z6135柴油机上的仿真和试验结果证明该建模方法是有效的.
A new method for modeling diesel engines was adopted, based on the crank-angle domain. The identification of closed-loop low order model of the control system of diesel engines was analyzed. Time domain analysis was used for the identification instead of conventional frequency domain analysis. Parameter estimation was carried out by least squares approximations. A dynamic model was established to optimize the parameters of the electronic governor of diesel engines. Simulation results were compared with the testing data of 16V240ZA and Z6135 diesel engines.
