Pumping a playground swing.
In mechanical studies of pumping a playground swing, two methods of energy insertion have been identified: parametric pumping and driven oscillation. While parametric pumping involves the systematic raising and lowering of the swinger's center of mass (CM) along the swing's radial axis (rope), driven oscillation may be conceived as rotation of the CM around a pivot point at a fixed distance to ...
متن کاملDiscrete-Decision Continuous-Actuation control: balance of an inverted pendulum and pumping a pendulum swing
In some practical control problems of essentially-continuous systems, the goal is not to tightly track a trajectory in state space, but only some aspects of the state at various points along the trajectory, and possibly only loosely. Here we show examples in which classical discrete-control approaches can provide simple, low inputand low outputbandwidth control of such systems. The sensing occu...
متن کاملSeverity of playground-related fractures: more than just playground factors?
INTRODUCTION Despite the establishment of playground safety standards, playground-related injuries are still a significant cause of extremity fractures in Singapore. This prospective study evaluates the dimensions and characteristics of our playgrounds, and their effect on fracture severity in an Asian population. We aim to correlate various playground risk factors with severity of the fracture...
متن کاملModern Telecommunications: A Playground for Physicists?
This report summarizes some of the material that was presented by the author during the 2015 Les Houches Summerschool on “Random Matrices and Stochastic Processes”. In these Lectures, various applications of Random Matrix Theory in modern telecommunications are reviewed. The aim is to introduce the Physics community to a number of relevant problems that can be analyzed using such tools, while a...
متن کاملAnti-swing Fuzzy Controller Design for a 3D Overhead Crane
This paper proposes a simple but efficient technique to control 3D overhead crane. Load must track a desired path and not sway more than a reasonable range.The proposed method uses PID control for trolley to track the desired path and fuzzy control compensation to eliminate the load swing. Only the projection of swing angle is applied to design the fuzzy controller. No plant information of cran...
