中文摘要:采用机械操纵系统的飞机相对电传控制飞机不具备飞行包线保护功能,驾驶员可能在误操作情况下使飞机进入失速状态,特别是新机研制试飞和失速飞行试验。失速自动改出装置通过控制反驱作动器带动操纵系统,抑制驾驶员将飞机操作进入失速,并在飞机进入失速后帮助驾驶员改出失速。模糊控制理论具备常规控制理论所不具备的很多优势,可以使控制律更简单、直观和有效,用于失速改出控制将使系统更加简单易行。
英文摘要:Compared with the aircraft which used wire flight control system, the aircraft that had mechanical control system was not provided with the flight envelope protection function, so the pilot may made the aircraft in stall with incorrect operation, especially in the trial test and the stall flight test when designing a new type of aircraft.Stall auto-protecting device can control reverse driving actuator to push the mechanical control system, restrain the pilot from leading the aircraft into stall, and eventually help the pilot to make the aircraft recover from stall. Fuzzy control theory has much more superiority than the conventional control theory, which can simplify the control law in a more efficient and direct way.
