Design and application of a disturbance rejection rotor speed control method for turbo-shaft engines

摘要: 主要研究了涡轴发动机控制问题.自抗扰控制(ADRC)是近年来新兴的控制方法,在不改变原有发动机串级比例积分微分(PID)控制结构的基础上,提出并构建了一种串级PID+扭矩ADRC补偿的控制结构,该结构充分利用了ADRC控制强的干扰补偿能力.最后,在直升机/发动机综合模型仿真环境下,通过模拟直升机大幅急速升降操作,验证了该算法具有比较理想的抗扰控制效果,能够较好地抑制直升机操控过程中大的扭矩扰动对涡轴发动机造成的不利影响.

Abstract: Turbo-shaft engine's control methodology was mainly studied in this article.Active disturbance rejection control(ADRC) method has been emerging in recent years.A hybrid control structure,i.e.an cascade proportion integration differentiation(PID) combined with torque's ADRC compensation,was proposed to improve the engine's disturbance rejection ability,and keep the formal control structure of the engine unchanged.The control system takes advantage of the excellent strong disturbance compensation property.The control system has better dynamic disturbance rejection ability than traditional system by simulation of helicopter's rapid lifting up and down based on the integrated helicopter/ turbo shaft engine platform. -
