Nonlinear Dynamic Inversion Control of a Miniature Morphing Aircraft

Aircraft Flight Control in Wind Shear Using Sequential Dynamic Inversion

Longitudinal wind shear flight control laws are developed for the dynamics of a twin-jet transport aircraft using nonlinear dynamic inversion. Time-scale decomposition simplifies controller design by partitioning it into slow and fast time scales. The effects of time-varying winds are explicitly considered in the derivation of the controllers. Three inverting controllers are developed and evalu...

Cascaded Incremental Nonlinear Dynamic Inversion Control for MAV Disturbance Rejection

Micro Aerial Vehicles (MAVs) are limited in their operation outdoors near obstacles by their ability to withstand wind gusts. Currently widespread position control methods such as Proportional Integral Derivative control do not perform well under the influence of gusts. Incremental Nonlinear Dynamic Inversion (INDI) is a sensor-based control technique that can control nonlinear systems subject ...

Causal approximate inversion for control of structurally flexible manipulators using nonlinear inner-outer factorization

A control scheme for flexible-link manipulators is advanced which is based on the notion of nonlinear inner–outer factorization. It is well known that the inverse of the forward dynamics map from joint torques to manipulator tip motion is noncausal and cannot be implemented in conjunction with real-time path planning. The methods used here determine causal approximations for the inverse dynamic...

Adaptive attitude controller of a reentry vehicles based on Back-stepping Dynamic inversion method

This paper presents an attitude control algorithm for a Reusable Launch Vehicle (RLV) with a low lift/drag ratio (L/D < 0.5), in the presence of external disturbances, model uncertainties, control output constraints and the thruster model. The main novelty of proposed control strategy is a new combination of the attitude control methods included backstepping, dynamic inversion and adaptive cont...
