The objective of this paper is to present a full-stack, real-time kinodynamic planning framework and demonstrate it on a quadrotor for collision avoidance. Specifically, the proposed framework utilizes an offlineonline computation paradigm, neighborhood classification through machine learning, sampling-based motion planning with an optimal control distance metric, and trajectory smoothing to ac...

This paper deals with the design of a fault tolerant control (FTC) of a quadrotor aircraft system, considering the actuator faults. The attitude dynamic model of quadrotor, taking into account the various parameters which can affect the dynamics of this system in space is presented. Subsequently, based on robust adaptive-backstepping method and taking into account the actuator faults, a new FTC...

In this paper, the particular solution technique for inverse simulation applied to the quadrotor maneuvering flight is investigated. The ‎trust-region dogleg (DL) technique which is proposed alleviates the weakness of Newton’s method used for numerical differentiation of system states in the solution process. The proposed technique emphasizes global convergence solution to the inverse simulatio...

This paper describes an integrated path planning and tracking control framework for autonomous verticaltake-off-and-landing (VTOL) vehicles, specially a quadrotor. The path planning adopts a receding horizon strategy to repeatedly plan a local trajectory that satisfies the vehicle dynamics and obstacle avoidance requirement. A tracking controller is then designed to track the optimised path. Th...

We describe a trajectory planning pipeline for large quadrotor teams in obstacle-rich environments. We construct a sparse roadmap in the environment and use a boundedsuboptimal conflict-based graph search to generate a discrete plan. We then refine this plan into into smooth trajectories using a spatial partition and Bézier curve basis. We model downwash directly, allowing safe flight in dense ...

The work proposed in this paper aims to design a robust stabilization of an underactuated quadrotor UAV system in presence of sensor failures. The dynamical model of quadrotor while taking into account various physical phenomena, which can influence the dynamics of a flying structure is presented. Subsequently, a new control strategy based on backstepping approach is developed. Lyapunov based s...

In this paper the cascaded fuzzy controller system for quadrotor steering and stabilizing was deliberated. The mathematical model of quadrotor and its cascaded fuzzy controller were simulated using Matlab Simulink software. The fuzzy system was divided into three subsystems for controlling position and speed of the quadrotor and for steering rotation speed of propellers. In the article the squa...

In this work, we develop and assess models for a real quadrotor in a Multi-Step prediction problem, that is, predicting the system state over many future steps using only the input. We propose a hybrid model with two configurations by combining deep recurrent neural networks with a quadrotor motion model. The proposed models take only motor speeds as input and predict the system state over a pr...

This paper describes the design, construction and validation of a mobile sensory platform for greenhouse monitoring. The complete system consists of a sensory system on board a small quadrotor (i.e., a four rotor mini-UAV). The goals of this system include taking measures of temperature, humidity, luminosity and CO2 concentration and plotting maps of these variables. These features could potent...

Stabilization and trajectory control of a quadrotor carrying a suspended load with a fixed known mass has been extensively studied in recent years. However, the load mass is not always known beforehand or may vary during the practical transportations. This mass uncertainty brings uncertain disturbances to the quadrotor system, causing existing controllers to have worse stability and trajectory ...
