摘要:

针对直升机飞-发一体化控制和边界保护控制问题,提出了一种基于投影算子的新型边界保护控制律设计方法,基于反馈控制概念设计了指令约束器,通过对控制指令进行修正,实现边界保护控制。基于UH-60直升机和T700涡轴发动机的参数,建立了直升机-传动机构-发动机综合系统的数学模型,采用动态逆和线性二次型调节器(LQR)控制理论设计了直升机飞-发一体化控制律,与基于投影算子的边界保护控制模块进行整合形成完整控制律。采用数值仿真检验了控制律的控制性能,仿真结果表明本文设计的控制律能够实现直升机和发动机的综合控制,在高度、滚转、俯仰、偏航通道实现显模型跟踪控制性能的同时,实现了高度变化率、姿态角、姿态角速率和发动机动力涡轮转速边界保护控制要求。

Abstract:

A novel envelope protection control method is proposed in this work. Such a control method is designed based on concepts of projection operators and command governors, achieving envelope protections by modifying control commands. A mathematical model is developed for a helicopter-transmission-engine integrated system based on parameters of the UH-60 helicopter and the T700 turboshaft engine. An integrated flight-engine control law is designed based on dynamic inversion and LQR control theories, and integrated with the projection operator-based envelope protection module. Numerical simulations are conducted to examine the performance of the control law. Simulation results indicate that the integrated helicopter-engine control law designed in this work achieves explicit modeling following performance in altitude, roll, pitch, and yaw control channels, and ensures envelope protections for altitude rates, fuselage attitudes, fuselage attitude rates, and engine power shaft speed.

Key words: helicopter-transmission-engine integrated systems, integrated flight-engine control, envelope protection control, explicit model following, dynamic inversion control, projection operators
