一种航空起动发电机的二自由度H∞鲁棒控制

摘要

为了进一步提高航空起动发电机的性能，提出了二自由度H∞鲁棒控制方法。基于模型匹配二自由度方案，通过标准H∞控制率研究了系统的鲁棒控制策略，建立了基于模型匹配二自由度系统的控制结构，并将控制率设计归结为标准的H∞控制问题。对控制方法进行仿真研究，结果表明控制系统能够具有良好的动态性能并且对于扰动具有较强的鲁棒性。%ln order to improve the performance of aero starter-generator,two-degree-of-freedom H∞ robust control had been presented. Based on scheme of model-matching two-degree-of-freedom,the robust control strategy had been researched through standardization H∞control rate,established a two-degree-of-freedom system control structure based on model matching and the design of speed controller was converted into a standard H∞ control problem. The control method had been simulated,the results indicate that control system has good dynamic performance,and the system has strong robustness under disturbance.
