This paper describes an approximated-scalar-sign-function-based anti-windup digital control design for analog nonlinear systems subject to input constraints. As input saturation occurs, the non-smooth saturation constraint is modeled with the approximated scalar sign function which is a smooth nonlinear function. The resulting nonlinear model is further linearized at any operating point with th...

1. Abstract This study proposes the improvement method of computational efficiency for the hybrid-type multiobjective particle swarm optimization method (MOPSO) that the authors developed for the reliability-based multiobjective optimization (RBMO). The hybrid MOPSO integrates the constraint satisfaction technique using gradient information of constraints with a concept of the single-loop-singl...

The traditional way of scheduling production processes often focuses on profit-driven goals (such as cycle time or material cost) while tending to overlook the negative impacts of manufacturing activities on the environment in the form of carbon emissions and other undesirable by-products. To bridge the gap, this paper investigates an environment-aware production scheduling problem that arises ...

RÉSUMÉ. Cet article présente une approche de résolution des problèmes d’optimisation multicritères basant su l’outil LMI. Notre objectif est de chercher un contrôleur stabilisant le système avec des contraintes fréquentielles et/ou temporelles. Cette conception est fondée sur la paramétrisation de Youla; cette paramétrisation est basée sur un contrôleur initial défini par la combinaison convexe...

In this paper we address the problem of clustering closed-loop consensus networks where the closed-loop controller is designed using a class of Linear Quadratic Regulator (LQR). Given any positive integer r, our objective is to develop a strategy for grouping the states of the n-node network into r ≤ n distinct non-overlapping groups. The criterion for this partitioning is defined as follows. F...

The aim of the present work is to continue the development of the prototype ALIV3, focusing on the estimation and control of the attitude. First the differences in motion and configurations of a tilt-quadrotor in relation with a common quadrotor are explained. The mass properties and actuators of the prototype are measured through tests specially developed. In the identification of the motors t...

An AFS (active front steering) on the basic of a C-EPS (column electric power steering) system was developed. Based on the mathematical model of essential components, the AFS controller was designed covering two units: an EPS actuator unit was used to reduce the steering torque requirement to the driver; an AFS actuator unit was used to compensate the steering angle for steering characteristics...

This paper presents a novel scheduling of resource-constrained Flexible Manufacturing System (FMS) with consideration the following sub-problems: (i) machine loading and unloading, (ii) manufacturing operation scheduling, (iii) assignment, (iv) Automated Guided Vehicle (AGV) scheduling. In proposed model, both AGV machinery are considered as required resources. Energy efficiency AGVs has been s...
