基于内模原理的涡轴发动机状态反馈控制方法

Investigation of state feedback control based on internal model principle for an turbo-shaft Engine

某型涡轴发动机全权限数控系统采用了状态反馈控制方式.根据内模原理,引入伺服补偿器,使设计的控制系统不仅具有较强的鲁棒性,而且在用于指令跟踪时能消除稳态误差;根据性能指标要求设计了状态反馈控制器,从而提高控制系统的品质.与目前的PID控制方式相比较,半物理模拟试验结果表明该控制方式有显著的性能改进.

A turbo-shaft engine FADEC system is subjected to the state feedback control mode. Based on the internal principle, a servo-compensator was introduced such that the control system could present strong robustness, and also eliminate steady state errors when tracking with commands. According to performance index, a states feedback controller was also designed to improve the performance of the control system. As compared with PID control method,the test results show an outstanding performance of the control system.
