Abstract In this literature, guidance and control laws using a basic control system have been proposed for analyses and designs of a Quadrotor. The basic control system includes: (a)height Control system using velocity stabilizing in the inner loop; (b)roll, pitch and yaw attitude control systems using angular rate stabilizing in inner loops. Base upon the basic control system, the B X and B Y ...

In this paper, we present a detailed dynamic and aerodynamic model of a quadrotor that can be used for path planning and control design of high performance, complex and aggressive manoeuvres without the need for iterative learning techniques. The accepted nonlinear dynamic quadrotor model is based on a thrust and torque model with constant thrust and torque coefficients derived from static thru...

Quadrotor is a type of rotor craft that consists of four rotors and two pairs of counter-rotating, fixed-pitch blades located at the four corners of the body. The flight control parameters optimization is one of the key issues for quadrotor. Estimation of distribution algorithm is a new kind of evolutionary algorithm developed rapidly recently. However, low convergence speed and local optimum o...

Abstract. In this paper we present a new control approach for a quadrotor mini-helicopter using the model predictive control (MPC) technique. The formulation employed is based on a linear prediction model obtained by linearizing the plant’s dynamics around an equilibrium point. The optimal control sequence is implemented in a receding-horizon strategy. The optimization is repeated at each sampl...

This paper describes the technical details of a quadrotor system capable of exploring unstructured indoor environment, detecting and replacing a specific USB flash disk, without relying on any external navigation aids. A Gmapping Simultaneous Localization and Mapping (SLAM) algorithm fused with various onboard sensor data is used to provide relative position, velocity and altitude of the vehicl...

This paper presents the design of a Fuzzy PID controller (FPID) based on fuzzy logic with a PID structure with many valued logic and reasoning. The self-turning Fuzzy PID control take in an error and the rate of change of error of the altitude and attitude of the quadrotor as the input to the fuzzy controller and use the fuzzy rules to adjust the PID parameter automatically. Simulations have be...

This paper addresses a team of cooperating vehicles performing autonomous deliveries in urban environments. The cooperating team comprises two vehicles with complementary capabilities, a truck restricted to travel along a street network, and a quadrotor micro-aerial vehicle of capacity one that can be deployed from the truck to perform deliveries. The problem is formulated as an optimal path pl...

Quadrotor UAVs are one of the most preferred type of small unmanned aerial vehicles because of the very simple mechanical construction and propulsion principle. However, the nonlinear dynamic behavior requires a more advanced stabilizing control and guidance of these vehicles. In addition, the small payload reduces the amount of batteries that can be carried and thus also limits the operating r...

Control and trajectory generation algorithms for a quadrotor helicopter with variable-pitch propellers are presented. The control law is not based on near-hover assumptions, allowing for large attitude deviations from hover. The trajectory generation algorithm fits a time-parametrized polynomial through any number of waypoints in R, with a closed-form solution if the corresponding waypoint arri...

In this paper we analyze attitude tracking of a quadrotor unmanned aerial vehicle by employing a recently developed feedback strategy based upon hybrid systems theory. The hybrid feedback control strategy employs a family of synergistic potential functions on the special orthogonal group of order three, SO(3), that guarantees global asymptotic stability of a rigid bodies attitude to a given ref...
