Abstract:

Rotary Cranes (Tower Cranes) are common industrial structures that are used in building construction, factories, and harbors. These cranes are usually operated manually. With the size of these cranes becoming larger and the motion expected to be faster, the process of controlling them became dicult without using automatic control methods. In general, the movement of cranes has no prescribed path. Cranes have to be run under dierent operating conditions, which makes closed-loop control preferable. In this work, two types of controllers are studied: fuzzy logic and time-delayed position feedb

Abstract:

Ship-mounted cranes are used to transfer cargo from large container ships to smaller lighters when deep-water ports are not available. The wave-induced motion of the crane ship produces large pendulations of hoisted cargo and causes operations to be suspended. In this work, we show that in boom type ship-mounted cranes, it is possible to reduce these pendulations significantly by controlling the slew and luff angles of the boom. Such a control can be achieved with the heavy equipment that is already part of the crane so that retrofitting existing cranes would require a small effort. Moreover

Abstract:

The main problem evaluated in this manuscript is the stabilization of periodic orbits of non-linear dynamical systems by use of feedback control. The goal of the control methods proposed in this work is to achieve a stable periodic oscillation. These control methods are applied to systems that present unstable periodic orbits in the state space, and the latter are the orbits to be stabilized.The methods proposed here are such that the resulting stable oscillation is obtained with low control effort, and the control signal is designed to converge to zero when the trajectory tends to the stabili

Abstract:

The main objective of this work is to design robust, fast, and practical controllers for gantry and tower cranes. The controllers are designed to transfer the load from point to point as fast as possible and, at the same time, the load swing is kept small during the transfer process and completely vanishes at the load destination. Moreover, variations of the system parameters, such as the cable length and the load weight, are also included. Practical considerations, such as the control action power, and the maximum acceleration and velocity, are taken into account. In addition, friction eff

Abstract:

It is sometimes necessary to transfer cargo from a large ship to a smaller ship at sea. Specially designed craneships are used for this task, however the wave-induced motions of the ship can cause large pendulations of cargo being hoisted by a ship-mounted crane. This makes cargo transfer in rough seas extremely dangerous and therefore transfer operations normally cease when sea state 3 is reached. If the cargo pendulations could be reduced in higher sea states, transfer operations would be possible. By controlling the boom luff angle, one can reduce the cargo pendulations in the plane of the

Abstract:

Diplomová práce pojednává o teorii chaotických dynamických systémů, speciálně se pak zabývá Rösslerovým systémem. Kromě standardních výpočtů spojených s bifurkační analýzou se práce zaměřuje na problém stabilizace, konkrétně na stabilizaci rovnovážných bodů. Ke stabilizaci je využita základní metoda zpětnovazebního řízení s časovým zpožděním. Významnou část práce tvoří zavedení a implementace obecné metody pro hledání vhodné volby parametrů vedoucí k úspěšné stabiliaci. Dalším diskutovaným tématem je možnost synchronizace dvou Rösslerových systémů pomocí různých synchronizačních schémat.

Ce travail a pour objet l’étude des techniques rapides pour calculer l’état cyclique établi des problèmes d’évolution en mécanique non-linéaire avec des conditions de périodicité en espace-temps. Un exemple typique est le roulage stationnaire d’un pneu présentant des sculptures périodiques, où l’état en chaque point est le même que l’état observé au point correspondant de la sculpture suivante une période en temps auparavant.L’application de solveurs directs pour la solution de tels problèmes est impossible car ils exigent l’inversion des matrices gigantesques.

Abstract:

<p dir="ltr">The aim of this research is to develop new techniques on chaos control and synchronization. One difference between chaos control and the traditional control is that in traditional control the reference signal is explicitly expressed, which is available directly; and in chaos control, in many cases, the reference signal is one of its unstable periodic orbits (UPOs), which needs to work out with methods such as delay coordinate embedding technique or to be replaced by the historical data as the analytic expression of the signal cannot be obtained directly (more details can be found

Abstract:

碩士<br>國立高雄應用科技大學<br>電機工程系<br>97<br>The problem of designing decentralized state feedback controller for a class of complex uncertain time-delay systems is studied in this thesis. Based on the new Lyapunov-Krasovskii functional adopted in [14], and the lemmas in the litarature [4, 11], we offer an alternated design method. A less conservative delay- independent linear matrix inequality (LMI) criterion is obtained compared to the litarature. We also design a state feedback controller such that the closed -loop uncertain system is asymptotically stable and also guarantees an -norm bound constrai
