Linear quadratic regulator control technique for stabilization a quadrotor aircraft

Control System Design for a Surface Effect Ship by Linear-Quadratic Regulator Method

In this paper, the main goal is to reduce the heave motion between a surface effect ship (SES) and a wind turbine in order to safely transfer equipment and person to SES. For this purpose, an LQR control system is designed to damp the vertical motion of the surface effect ship in critical sea states including high-frequency and high amplitude regular waves as well as high frequency irregular wa...

Mathematical Model and Vibration Analysis of Aircraft with Active Landing Gear System using Linear Quadratic Regulator Technique

This paper deals with the study and comparison of passive and active landing gear system of  the aircraft and dynamic responses due to runway irregularities while the aircraft is taxying. The dynamic load and vibration caused by the unevenness of runway will result in airframe fatigue, discomfort of passengers and the reduction of the pilot’s ability to control the aircraft. One of the objectiv...

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

Model Predictive Control applied to tracking and attitude stabilization of a VTOL quadrotor aircraft

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...
