摘要

摘要: 主要研究涡轴发动机转速抗扰控制问题,提出了一种基于自抗扰控制技术(ADRC, Adaptive Disturbance Rejection Control)的涡轴发动机增量型串级抗扰控制器设计方法.一方面,采用串级控制结构,内环控制块模态的燃气涡轮转速,外环控制功率涡轮转速,使得内环扰动得到快速抑制.另一方面,每个子回路中通过扩张状态量观测实时地对被控对象内环进行扰动补偿.最后,基于直升机/发动机非线性综合仿真模型的数字仿真表明该控制方法显著改善了涡轴发动机功率跟随特性,提升了直升机/涡轴发动机综合闭环系统的可操控极限.

Abstract: Disturbance rejection control problem of turbo-shaft engine speed was studied. A disturbance rejection control scheme of turbo-shaft engine was proposed based on increment cascade adaptive disturbance rejection control (ICADRC). For one thing, cascade control structure was used to ensure that the disturbance in the inner loop can be suppressed in time. In this control structure, gas turbine speed was controlled in the inner loop, while power turbine speed in the outer loop. For another, in both control loops the control object was compensated from disturbance in virtue of extended state observation. Finally, digital simulation of integrated helicopter/engine system shows that the new control scheme can improve the power following character of turbo-shaft engine evidently, and can enhance the handling limit of integrated helicopter/engine closed loop system.
