Command Shapers for Systems with Actuator Saturation
2007 American Control Conference, 2007Command shapers are used to create inputs that move flexible systems without residual vibration. Originally developed for linear systems, command shapers use superposition of the inputs to cancel vibration and control the system response. Nonlinearities in the system degrade the performance of traditional command shapers.

Control of linear systems with saturating actuators
Proceedings of 1995 American Control Conference - ACC'95, 1996The paper deals with (linear) systems of the form \(\dot x = Ax + B \sigma (u + g(x,t))\), \(y = Cx\), with \(x,u\) and \(y\) the state-, input- and output vector; \(\sigma\) is a saturation function and \(g\) represents the uncertainties/disturbances in the system.

Sliding surface design with saturated actuator
2012 12th International Workshop on Variable Structure Systems, 2012A class of nonlinear uncertain systems with saturated actuator is considered in this paper. Sliding surface matrix is obtained using parameterized Riccatti equation. The proposed surface ensures that control limits are respected in a region of state space. This region can be made sufficiently large by choosing appropriate value of design parameters.

Anti-windup in anticipation of actuator saturation
49th IEEE Conference on Decision and Control (CDC), 2010This paper considers control systems in the presence of actuator saturation. A traditional approach to alleviating the adverse effect of actuator saturation is to design an anti-windup mechanism and activate it as soon as the saturation occurs. A recent innovation is to delay the activation of the anti-windup mechanism until the degree of saturation ...

On Variable Structure Actuator Saturation Compensators
HKIE Transactions, 1997Most existing actuator saturation compensators are fixed structure with constant parameters. As the linear system now becomes nonlinear when the actuator saturates, using only one linear compensator may not be adequate to produce acceptable response.

Actuator saturation avoidance in overactuated systems
2004 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2005The 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 ...

System Types in Feedback Control With Saturating Actuators
IEEE Transactions on Automatic Control, 2004This paper extends the classical notation of system type to feedback control with saturating actuators. For step, ramp, and parabolic inputs, it defines the so called trackable domains and evaluates steady state errors. It shows that, unlike the linear case, the role of the poles at the origin of the plant and the controller are different and, on this ...
