Although most of the control design methods assume unbounded control signals, real systems do have saturating actuators, which may degenerate closed-loop performance or even lead to unstable behavior.

Design of Compensators for Actuator Saturation
Proceedings of the Institution of Mechanical Engineers, Part I: Journal of Systems and Control Engineering, 1995Actuator saturation is a common non-linear control problem; if it is not being compensated properly, the system can become unstable. When the actuator saturates, the control that cannot be implemented can be interpreted as a non-linear disturbance being injected into the closed-loop system.

Actuator Saturation Compensation For Fuzzy Controllers
IFAC Proceedings Volumes, 1994Abstract A general actuator saturation compensation scheme for fuzzy controllers which is an extension of that for linear controllers is presented in this paper. The condition for its implementation is given, and the necessary conditions for the compensated system to be absolute stable discussed.

This paper presents a predictor based structure that is suitable to deal with both time-delayed and delay-free systems with saturating actuators. Such condition, well known in the literature to cause the windup phenomenon, is usually coped within the ...

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.

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.

We address the problem of robust input-to-state stabilization of parameter-varying discrete-time systems with time-varying state delay, saturating actuators, and subject to $\ell _2$-limited disturbance.
