摘要
本文提出了对一种新型的泄压储能高增压柴油机的自适应控制方案。文章介绍了泄压储能系统数学模型的建立、分析和实验,找出了最佳系统参考模型,并研究了采用单输入单输出方程描述的模型参考自适应控制方案。通过计算机仿真表明,采用该方案使泄压储能高增压柴油机的最佳运行精度较高。
A novel adaptive control scheme is suggested in the paper for highly supercharged dissel engine (HSDE) with pressure-relieved and erergy-coumulatedmechanism (PEM). The modelling analysing and testing of the PEM systemare presented and the optimal system model is found. The model reference adap-tive control (MRAC) system described by single-input single-ou put equationmakes the engine operation model to approach the optimal operation model. TheMRAC technique causes the HSDB with PEM operating accurately and robustlyin optimal operation condition.
