Formation Control for Multiple Quadrotor Aircraft via Fixed-time Consensus Algorithm

A Digital Control Architecture for Quadrotor Aircraft

We show that the principal attitude and inertial dynamics of a quadrotor aircraft can be decomposed into a cascade of three passive and one interior conic subsystem such that a proportional digital feedback loop can effectively be applied to each subsystem in a nested manner. This proportional feedback architecture includes one saturation block nested between the attitude and inertial control s...

Finite-time output feedback stabilization and control for a quadrotor mini-aircraft

Fixed-time cluster synchronization for complex networks via pinning control

Abstract—In this paper, the fixed-time cluster synchronization problem for complex networks via pinning control is discussed. Fixed-time synchronization has been a hot topic in recent years, which means that the network can achieve synchronization in finite-time and the settling time is bounded by a constant for any initial values. To realize the fixed-time cluster synchronization, a simple dis...

Aggressive flight of fixed-wing and quadrotor aircraft in dense indoor environments

In this paper, we describe trajectory planning and state estimation algorithms for aggressive flight of micro aerial vehicles in known, obstacledense environments. Finding aggressive but dynamically feasible and collision-free trajectories in cluttered environments requires trajectory optimization and state estimation in the full state space of the vehicle, which is usually computationally infe...

Fault Tolerant Control for Quadrotor via Backstepping Approach

Different from the previous work for quadrotor which mostly discusses application of different controllers to quadrotor control under normal flight conditions, this paper introduces a new design strategy which considers fault tolerant capability of the quadrotor control problems. By utilizing Passive Fault Tolerant Control Systems (PFTCS) concept with backstepping control approach, the trajecto...
