摘　　要：为了提高发动机的转速调节性能并保证安全性,针对航空发动机控制系统,本文提出一种性能与安全协调切换控制策略,并设计一种无扰切换控制策略抑制切换造成的信号突变问题。首先,将发动机性能与安全协调控制问题描述成输出受限的状态跟踪切换控制问题,利用多Lyapunov函数方法分别设计性能回路和安全保护回路控制器。然后,为了避免切换导致控制信号突变对系统造成危害,提出一种基于可调插值函数的无扰切换控制策略,并给出无扰切换的稳定性充分条件。最后,将所提出的基于无扰切换的航空发动机性能与安全协调控制策略应用于航空发动机控制系统仿真试验中。结果表明,无扰切换策略的信号变化比直接切换的减少约21%,表明了所提方法的有效性。For the aero-engine control system,in order to improve the speed regulation performance of the engine and ensure safety,a switching control strategy for coordinating performance and safety is proposed,and a bumpless transfer control strategy is designed to solve the problem of the bump control signals caused by switchings.Firstly,the coordinated control problem of engine performance and safety is described as a state tracking switching control problem with limited output and based on the multiple Lyapunov function method,the controllers of the performance loop and the safety protection loop are designed respectively.Then,in order to avoid the damage to the system caused by the bump control signals,a bumpless transfer control strategy based on the adjustable interpolation function is proposed,and a sufficient condition for the stability of the bumpless transfer is given.Finally,the proposed Performance and safety coordination control design based on bumpless transfer strategy for aero-engines is applied to the simulation of aero-engine control system.The results show that the signal change of the bumpless transfer strategy is about 21%less than that of the direct switching control,which shows the effectiveness of the proposed method.
