摘要
基于发动机力矩控制的思想,通过对发动机实际物理模型和相关脉谱图数据的分析,建立了一个非线性的发动机模型.在模型的基础上,充分考虑模型参数的不确定性因素,设计了一个反馈线性化的发动机速度控制器,并利用积分器对系统进行增广,以减少速度跟踪的稳态误差.模型设计的控制器在enDYNA发动机模型上的仿真表明,所设计的控制器能够达到理想的控制性能.
In this paper, based on the idea of engine torque control, after analyzing the practical physical model and some of the engine runtime map data, a nonlinear engine model was built. On the basis of this nonlinear model, a feedback linearization controller was designed for engine speed control, with model parameter uncertain being sufficiently taken into account. In order to decrease the steady state errors of speed tracking, an augmented integral control approach was applied. Simulation results on the enDYNA engine model show us that suggested controller has achieved desired response performance.
