Control of Quadrotor Using Sliding Mode Disturbance Observer and Nonlinear Hâ
Authors
Abstract:
In this paper, a nonlinear model of the underactuated six degrees of freedom (6 DOF) quadrotor helicopter was derived based on the Newton-Euler formalism. A new nonlinear robust control strategy was proposed to solve the stabilizing and path following problems in presence of external disturbances and parametric uncertainties. The proposed control structure consist of a sliding mode control based on disturbance observer (SMDO) to track the reference trajectory together with a nonlinear Hâ controller to stabilize the rotational movements. Simulation results in the presence of aerodynamic disturbances and parametric uncertainties are presented to corroborate the effectiveness and the robustness of the proposed strategy.

full textDynamic Sliding Mode Control of Nonlinear Systems Using Neural Networks
Dynamic sliding mode control (DSMC) of nonlinear systems using neural networks is proposed. In DSMC the chattering is removed due to the integrator which is placed before the input control signal of the plant. However, in DSMC the augmented system is one dimension bigger than the actual system i.e. the states number of augmented system is more than the actual system and then to control of such ...

Robot-aided rehabilitation has become an important technology to restore and reinforce motor functions of patients with extremity impairment, whereas it can be extremely challenging to achieve satisfactory tracking performance due to uncertainties and disturbances during rehabilitation training. In this paper, a wire-driven rehabilitation robot that can work over a three-dimensional space is de...

A sliding mode control based on nonlinear disturbance observer is presented in this paper considering the tracking control of mobile manipulators. The proposed control strategy adopts the nonlinear observer to estimate the bounded external disturbances and overcome the effects. In addition, the stability of the controller is verified by Lyapunov theory. Finally, the simulation results verify th...
full textComparison of Quadrotor Performance Using Backstepping and Sliding Mode Control
A quadrotor is nonlinear, coupled and unstable system. Two control schemes, namely backstepping and sliding mode, have been applied to obtain desired trajectory tracking by quadrotor. This paper presents the comparative performance results of quadrotor under two control schemes.
