This paper proposes an adaptive filtering-based INDI control method for angular rate control of VTOL aircraft. To address the problem that angular acceleration signals cannot be accurately obtained in VTOL vehicle control, a Least Mean Square (LMS) error-based adaptive filtering algorithm is used to predict the angular rate, thus avoiding the requirements of general estimation and filtering methods on aircraft ontology model information and a priori knowledge. Therefore, in this paper, we firstly establish a model of the hovering phase of a VTOL vehicle that contains unconventional generalized maneuvering surfaces such as vector engines, lift fans, and roll nozzles. Then, the Adaptive Filtering-Incremental Nonlinear Dynamic Inverse (AF-INDI) control law is proposed and validated by simulation. The simulation shows the AF-INDI control method can predict angular rate signal well, significantly reduce the signal noise interference, and realize the angular rate control of the VTOL aircraft.

摘要

This paper proposes an adaptive filtering-based INDI control method for angular rate control of VTOL aircraft. To address the problem that angular acceleration signals cannot be accurately obtained in VTOL vehicle control, a Least Mean Square (LMS) error-based adaptive filtering algorithm is used to predict the angular rate, thus avoiding the requirements of general estimation and filtering methods on aircraft ontology model information and a priori knowledge. Therefore, in this paper, we firstly establish a model of the hovering phase of a VTOL vehicle that contains unconventional generalized maneuvering surfaces such as vector engines, lift fans, and roll nozzles. Then, the Adaptive Filtering-Incremental Nonlinear Dynamic Inverse (AF-INDI) control law is proposed and validated by simulation. The simulation shows the AF-INDI control method can predict angular rate signal well, significantly reduce the signal noise interference, and realize the angular rate control of the VTOL aircraft.
