A Review on Control Methods for Multi-Lift Rotorcraft Systems

摘要

This paper aims to give an overview of multi-lift rotorcraft (MLR) systems' theoretical research and associated flight tests in the past years, making it possible to inform researchers of future applications or strategies of related research. Analyzing some published papers searched on online databases, hot issues such as modeling, configurations, coordinated control and experiments of multi-lift rotorcraft systems are outlined. As a consequence, the major problems as well as development tendencies of multi-lift rotorcraft systems are analyzed and the future work is also pointed out. The summaries of existing modeling and control frameworks try to give researchers an insight into multi-lift rotorcraft systems.
