This chapter discusses how the principles of Adaptive Dynamic Programming (ADP) can be applied to the control of a quadrotor helicopter platform flying in an uncontrolled environment and subjected to various disturbances and model uncertainties. ADP is based on reinforcement learning. The controller (actor) changes its control policy (action) based on stimuli received in response to its actions...

Adaptive control techniques have the potential to address many of the special performance and robustness requirements of flight control for unmanned aerial vehicles. L1 adaptive control offers potential benefits in terms of performance and robustness. An L1 adaptive output feedback control design process is presented here in which control parameters are systematically determined based on intuit...

Analysis of quadrotor dynamics and control is conducted. A linearized quadrotor system is controlled using modern techniques. A MATLAB quadrotor control toolbox is presented for rapid visualization of system response. Waypoint-based trajectory control of a quadrotor is performed and appended to the MATLAB toolbox. Finally, an investigation of control using reinforcement learning is conducted.

The paper deals with the stabilisation and trajectory tracking control of an autonomous quadrotor helicopter system in presence wind disturbances. proposed adaptive controller uses radial basis function neural networks (RBF NNs) to approximate unknown nonlinear functions system. Two controllers are this handle modelling errors external disturbances: H∞ H∞-ANC H∞-based sliding mode H∞-ANSMC. des...

This paper presents a real-time vision based algorithm for 5 degrees-offreedom pose estimation and set-point control for a Micro Aerial Vehicle (MAV). The camera is mounted on-board a quadrotor helicopter. Camera pose estimation is based on the appearance of two concentric circles which are used as landmark. We show that that by using a calibrated camera, conic sections, and the assumption that...

This paper suggests a decentralized adaptive sliding mode formation procedure for affine nonlinear multi-quadrotor under a fixed directed topology wherever the followers are conquered by dynamical uncertainties. Compared with the previous studies which primarily concentrated on linear single-input single-output (SISO) agents or nonlinear agents with constant control gain, the proposed method is...

This paper provides new results for the tracking control of a quadrotor unmanned aerial vehicle (UAV). The dynamics of the quadrotor UAV are expressed globally on the configuration manifold of the special Euclidean group, and we construct geometric controllers to track outputs that correspond to each of three flight modes, namely (1) almost global asymptotic tracking of the attitude of the quad...
