摘　　要：针对某型涡轴发动机起动过程重复性差和不稳定的问题,本文引入闭环增益成形控制方法,设计基于转速速率闭环控制算法,并对所设计的控制器进行半物理模拟试验验证。试验结果表明,该方法稳定可靠,鲁棒性较好,发动机起动过程重复性和稳定性明显改善。In view of the poor reproducibility and instability in the turbo-shaft engine starting process, this paper introduces the closed-loop gain shaping control method, based on the speed rate closed-loop algorithm and designs the controller to control the starting process. In the semi-physical simulation, the system shows good stability, reliability and robustness, as well as the reproducibility and stability are improved obviously.
