Review and Progress of PIO Prevention for Helicopters with Fly-by-Wire Flight Control System
摘要
Abstract
Pilot induced oscillation(PIO)is a sustained or uncontrollable oscillation that occurs when the pilot is in the control loop.Compared to mechanical systems,fly-by-wire aircraft are more susceptible to PIO,a dangerous phenomenon that can cause loss of control or crashes.Therefore,preventing PIO is a critical objective in aircraft development.Based on experiences from helicopter development and flight testing,this article reviews the current state of PIO avoidance technologies for fly-by-wire helicopters.The review covers flight control systems,control laws,simulation,and flight testing,and also provides a future outlook.The findings offer guidance for effectively avoiding PIO during the design and development of fly-by-wire helicopters.关键词
