考虑切换特性的航空发动机多回路控制系统设计

Design of aero engine multi-loop controllers with switching characteristics

针对航空发动机多回路控制系统切换,分析了多回路控制系统切换的性能指标要求,基于极点配置与H鲁棒控制综合的方法,构造了线性矩阵不等式(LMIs),以此为充分条件给出了多回路切换时的H∞控制器设计方法,并与单回路系统设计切换进行比较仿真,进一步表明了航空发动机切换控制的必要性与有效性.

The switching problem of aero-engine multi-loops control system was studied, and the performance index requirements were also analyzed. Based on the pole placement and H∞ robust synthesis, linear matrix inequalities（LMI） were constructed to provide a firm basis for determining H∞ design method under multi-loop switching. As compared with traditional method of single-loop system, the simulation showed the feasibility and the necessity of the method hereto.
