| 摘 要： | 针对汽车发动机在怠速工况下的特点,利用混合系统模型来描述四缸火花点火汽油发动机系统所具有的物理规律和操作约束,并采用具有处理约束能力的预测控制策略对系统进行控制。在保证满足性能指标函数最小和系统约束的同时,使发动机转速尽可能接近给定的参考值,从而达到系统对发动机转速的稳定性,燃料消耗和排放的要求。实验结果表明了该方法的有效性和可行性。

| Abstract: | A hybrid model was established to describe the physical law and operation constraints of a 4-cylinder SI engine in idle speed mode. And an idle speed controller was designed based on model predictive control strategy,which can deal with the system constraints.Under the condition of satisfying the performance function minimization and system constraints,the engine speed was regulated to a reference value.The simulation result shows that the control strategy is effective and feasible for engine in idle speed ... |
