Lagrangian Reduction and the Double Spherical Pendulum
This paper studies the stability and bifurcations of the relative equilibria of the double spherical pendulum, which has the circle as its symmetry group. This example as well as others with nonabelian symmetry groups, such as the rigid body, illustrate some useful general theory about Lagrangian reduction. In particular, we establish a satisfactory global theory of Lagrangian reduction that is...
متن کاملPractical Sway Motion Control for Double Pendulum-type Overhead Crane System
The sway motion of crane can be successfully suppressed by properly shaping the reference command. Input shaping is a one type of feed-forward shaping method that is based on linear superposition. In this paper, we present the impact of double pendulum type overhead crane (DPTOC) system on the effectiveness of input shaping. An unshaped bang-bang input force is used to determine the characteris...
متن کاملTechniques For Sway Control Of A Double-Pendulum-Type Overhead Crane
This paper presents investigations into the development of input shaping techniques for swaying control of a doublependulum-type overhead crane (DPTOC) system. A nonlinear DPTOC system is considered and the dynamic model of the system is derived using the Euler-Lagrange formulation. An unshaped bang-bang input force is used to determine the characteristic parameters of the system for design and...
متن کاملMA3-6 : Reduction of Double-Pendulum Bridge Crane Oscillations
The natural sway of crane payloads is detrimental to safe and efficient operation. Under certain conditions, the problem is complicated when the payloads create a double-pendulum effect. Most crane control research to date has focused on single-mode dynamics. For example, several researchers have shown that signal-mode oscillations can be greatly reduced by properly shaping the inputs to the cr...
متن کاملSpherical Pendulum Small Oscillations for Slewing Crane Motion
The present paper focuses on the Lagrange mechanics-based description of small oscillations of a spherical pendulum with a uniformly rotating suspension center. The analytical solution of the natural frequencies' problem has been derived for the case of uniform rotation of a crane boom. The payload paths have been found in the inertial reference frame fixed on earth and in the noninertial refer...
