摘要:
基于2自由度的发动机简化模型,针对发动机的外部干扰信号由线性外系统的输出描述, 通过引入扰动补偿信号,给出发动机系统的前馈反馈最优控制器的设计方法.该控制器由状态反馈项和扰动输入前馈补偿项构成,前馈项用于补偿干扰输入对发动机的影响,控制器的反馈和前馈增益可通过求解代数方程得到.仿真算例表明:该方法对抑制发动机的外部干扰有很好的鲁棒性.
Abstract:
The model is based on a simplified two-degree-of-freedom active automobile engine. And the external interference signal is described by the output of linear external system. The designing method of the feedforward and feedback optimal controller is obtained by introducing disturbance compensation signal. The controller consists of a state feedback term and a disturbance input feedforward compensation term. The feedforward term is used to compensate the influence of disturbance input to engine. Controller feedback and feedforward gain can be obtained by solving algebraic equations. The simulation demonstrates that the typical model has very good robustness to restrain the disturbance input.
