An LQR theory for systems with asymmetric saturating actuators
2016 American Control Conference (ACC), 2016This paper presents an LQR-based method, referred to as A-SLQR, for systems with asymmetric (i.e., non-odd) saturating actuators. The development is based on a technique referred to as stochastic linearization, which approximates the saturation function by an equivalent gain and an equivalent bias.

Synthesis Algorithm for Control System with Saturated Actuator
Differential Equations and Control ProcessesThe paper presents a generalized algorithm for designing closed optimal systems with a dynamic controller and a nonlinear actuator. The purpose of the proposed algorithm is to identify the area of system performance degradation, manifested as unintentional oscillations, due to the influence of actuator nonlinearity and reduce this area.

Dynamic anti-windup design in anticipation of actuator saturation
Proceedings of the 2011 American Control Conference, 2011SUMMARYIn a traditional anti‐windup design, the anti‐windup mechanism is set to be activated as soon as the control signal saturates the actuator. A recent innovation of delaying the activation of the anti‐windup mechanism, both static and dynamic, until the saturation reaches a certain level of severity has led to a performance improvement of the ...

Smart management of actuator saturation in integrated vehicle control
IEEE Conference on Decision and Control and European Control Conference, 2011Integrated control design to guarantee vehicle stability is one of the main topics in vehicle control. Actuators saturation is a main concern when dealing with this issue. In this work, we propose a fully integrated control by means of three actuators: Active Front Steering (AFS), Rear Torque Vectoring (RTV) and Semi-Active Suspensions (SAS).

Prevention of Windup Caused by Saturating Sensors and Actuators (With Saturation Indicator)
2021Good disturbance rejection requires large plant input signals. It can therefore happen that also the always-existing input saturation is activated by the external disturbances. Thus, the loop must exhibit a stable behavior in the presence of joint input and output saturation.

Actuator Saturation and Control System Performance
1993 American Control Conference, 1993Lyapunov's Direct Principle is applied to the problem of establishing bounds of convergence which result from the saturation of actuators. The treatment is applicable to those cases for which a linear time invariant nominal model is appropriate. The results are demonstrated with a four-state example.

Multiscale optimization of saturated poroelastic actuators [PDF]
, 2011 A multiscale method for optimizing the material micro structure in a macroscopically heterogeneous saturated poroelastic media with respect to macro properties is presented. The method is based on topology optimization using the homogenization technique, here applied to the optimization of a bi-morph saturated poroelastic actuator.
