Taschenbuch. Condition: Neu. Neuware -The first part of this book discusses a numerical approach to solve two-dimensional heat conduction problems of layer composites with steady and transient states by implementing a Meshless Local Petrove-Galerkin (MLPG) method. At the second part, a similar approach is applied for analysis of three-dimensional steady state heat conduction problems. The penalty method is adopted to efficiently enforce the essential boundary condition. Among interpolation functions, due to the high continuity of the approximation function, the moving least squares (MLS) interpolation is selected. Also the Heaviside step function is considered as the test function. To resolve the problem of discontinuity in layers of composites, a new technique is proposed for the numerical integration process. To deal with time derivatives, the forward time differences are employed. Several numerical examples have been illustrated in both parts to prove the efficiency and accuracy of the considered approach.Books on Demand GmbH, Überseering 33, 22297 Hamburg 100 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -A fuzzy controller for anti-swing and positioning control of an overhead traveling crane is proposed based on the SIRMs (Single Input Rule Modules) dynamically connected fuzzy inference model. The trolley position and velocity, the rope swing angle and angular velocity are selected as input items, and the trolley acceleration as output item. With a simple structure, the controller can autonomously adjust the influence of each input item. The control system is further proved to be asymptotically stable near destination. Multi-objective genetic algorithm optimization is successfully implemented to find the controller gains. Control simulation results show that the controller is robust to different rope lengths and has generalization ability for different initial positions. Compared with linear state feedback controller, the fuzzy controller can drive the crane to destination in short time with small swing angle.Books on Demand GmbH, Überseering 33, 22297 Hamburg 100 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Es wird ein Fuzzy-Regler für die Anti-Schwenk- und Positionierungssteuerung eines Laufkrans vorgeschlagen, der auf dem dynamisch verbundenen Fuzzy-Inferenzmodell SIRMs (Single Input Rule Modules) basiert. Die Katzposition und -geschwindigkeit, der Seilschwingungswinkel und die Winkelgeschwindigkeit werden als Eingangsgrößen und die Katzbeschleunigung als Ausgangsgröße gewählt. Mit einer einfachen Struktur kann der Regler den Einfluss jedes Eingangselements selbständig anpassen. Das Steuersystem erweist sich außerdem als asymptotisch stabil in der Nähe des Ziels. Multi-objektive genetische Algorithmus-Optimierung wird erfolgreich implementiert, um die Reglergewinne zu finden. Die Simulationsergebnisse zeigen, dass der Regler robust gegenüber unterschiedlichen Seillängen ist und die Fähigkeit zur Generalisierung für unterschiedliche Ausgangspositionen besitzt. Im Vergleich zu linearen Zustandsreglern kann der Fuzzy-Regler den Kran in kurzer Zeit mit kleinem Schwenkwinkel zum Ziel führen.Books on Demand GmbH, Überseering 33, 22297 Hamburg 64 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The multi-objective genetic algorithm defined in toolbox of MATLAB software has been employed to optimally design of passive and active models of car-quarter and car-half vehicle. So, by this type of optimization in both the active models, a PID controller has been designed to improve ride comfort.These results show the superiority of the obtained two active suspension models which have been done by this work in comparison with either their presented passive models or those best passive models (2-DOF and 5-DOF) published up to now. 76 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Un contrôleur flou pour l'anti-basculement et le contrôle de positionnement d'un pont roulant est proposé sur la base du modèle d'inférence floue à connexion dynamique SIRMs (Single Input Rule Modules). La position et la vitesse du chariot, l'angle d'oscillation du câble et la vitesse angulaire sont sélectionnés comme éléments d'entrée, et l'accélération du chariot comme élément de sortie. Avec une structure simple, le contrôleur peut ajuster de manière autonome l'influence de chaque élément d'entrée. Il est également prouvé que le système de contrôle est asymptotiquement stable à proximité de la destination. L'optimisation par algorithme génétique multi-objectif est mise en oeuvre avec succès pour trouver les gains du contrôleur. Les résultats de la simulation de contrôle montrent que le contrôleur est robuste aux différentes longueurs de corde et a une capacité de généralisation pour différentes positions initiales. Comparé au contrôleur linéaire à rétroaction d'état, le contrôleur flou peut conduire la grue à destination en peu de temps avec un petit angle d'oscillation. 64 pp. Französisch.
