Abstract

The incremental nonlinear dynamic inversion (INDI) method has been widely applied across various fields and is theoretically capable of achieving precise control of complex nonlinear systems. However, its performance is affected when control effectiveness is uncertain or actuator bandwidth is constrained. In this paper, we propose an adaptive nonlinear dynamic inversion algorithm with actuator dynamics (ANDIa) that incorporates a virtual control matrix and a nonlinear system estimator to address these limitations. Comparative analyses with the INDI controller demonstrate that ANDIa significantly improves control performance under conditions of uncertain control effectiveness and limited actuator bandwidth.
