Actuator saturation avoidance in overactuated systems

2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005
The presence of redundant actuators in dynamic systems increases system efficiency and capability. An example of this increased capability is avoidance of actuator saturation at critical moments. Defining a system maximum efficiency function, this paper transforms the problem of avoiding actuator saturation into an optimization problem with the ...

Control of quadrotors with actuator saturations

The 27th Chinese Control and Decision Conference (2015 CCDC), 2015
Actuator saturation is a common problem in the actual system of quadrotors. In this paper, we study the control method of quadrotors with actuator saturations, and we propose a static rescaling method. Firstly, the system control of quadrotors is divided into the attitude and position control.

An Uncertainty Model for Saturated Actuators

1989 American Control Conference, 1989
An uncertainty model for saturated actuators is reported in this paper. The model includes linear as well as quasi-linear elements where the quasi-linear elements are used to model the effects of rate and deflection limiting within the actuator. Since the actuator uncertainty model is quasi-linear, the magnitudes of the signals within the actuator ...

Adaptive coordinated attitude control for spacecraft formation with saturating actuators and unknown inertia

Journal of the Franklin Institute, 2019
In this paper, an adaptive attitude coordination control problem for spacecraft formation flying is investigated under a general directed communication topology containing a directed spanning tree with a leader as the root.

Finite-time feedback stabilization of a class of input-delay systems with saturating actuators via digital control

IEEE/CAA Journal of Automatica Sinica, 2019
In this paper, the problem of making an input-delay system with saturating actuators finite-time stable by virtue of digital control is investigated. A digital state feedback controller and digital observer-controller compensator are designed for two ...

Manual control with saturating actuators

1997 European Control Conference (ECC), 1997
The objectives of this paper are to concisely state the tracking control problem with actuator saturation, briefly review the current literature, and formulate the problem in a manual (flight) control context. The complexity of tracking control with saturation is demonstrated via a "simple" example.

Synchronous optimal control method for nonlinear systems with saturating actuators and unknown dynamics using off-policy integral reinforcement learning

Neurocomputing, 2019
The present study establishes an approximate optimal critic learning algorithm, based on the single-network integral reinforcement learning (IRL) algorithm and intends to solve the optimal control problem for an unknown nonlinear system with saturating ...

Assisting saturated control for a linear system with saturating actuators

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
For a linear system with saturating actuators, a new control scheme, AS (assisting saturated) control is proposed. The AS control has a modified form of an ARE (algebraic Riccati equation) based saturating control in the case that some control input channels are not saturated.

Performance degradation due to measurement noise in control systems with disturbance observers and saturating actuators

Journal of the Franklin Institute, 2019
Augmenting feedback control systems with disturbance observer (DOB) is a widely used technique in system design to compensate for the effect of exogenous disturbances as well as plant model uncertainties.

Finite‐time stabilisation of switched linear input‐delay systems via saturating actuators

IET Control Theory & Applications, 2018
In this study, the problem of finite-time feedback stabilisation for switched linear input-delay systems with saturating actuators is addressed by virtue of the comparison-function-like method.
