An Aerodynamic load tracking method for electric tail rotor of helicopter

摘要: In this paper, an electric propulsion system using high power-density permanent magnet motor for helicopter’s tail rotor is introduced. Electric rotor(ETR) demands to provide synchronous power under the continuous adjustment of pitch angle and sudden-changing aerodynamic disturbance, thus Liner Extended State Observer (LESO) used estimate fluctuation drive system, a Pitch Angle Estimator (PAE) also designed tune bandwidth LESO. The proposed method has been verified on simulation platform results show that achieves fast dynamic response disturbance rejection different conditions, which makes it applicable other electrical devices with large-scale varying load.
