Capture zone of linear strategies in interception problems with variable structure dynamics     

Josef Shinar  Valery Y. Glizer  Vladimir Turetsky 《Journal of The Franklin Institute》2014

The paper considers planar interception engagements against maneuverable targets using a linearized kinematic model with constant velocities. Both the interceptor and the target have bounded controls and first-order linear dynamics. Due to the linearization, the duration of the interception is prescribed. The target dynamics is fixed, but the interceptor has variable structure dynamics, switching from one mode to another once during the engagement. For such engagements the capture zone of a given linear feedback control is constructed. Numerical examples demonstrate that proper change of the interceptor dynamic mode leads to an enlarged capture zone.  相似文献

Single landmark feedback-based time optimal navigation for a differential drive robot     

Vladimir Macias  Israel Becerra  Edgar Martinez  Rafael Murrieta-Cid  Hector M. Becerrra 《Journal of The Franklin Institute》2021,358(9):4761-4792

In this paper, we propose a feedback-based control approach to execute the time optimal motion trajectories for a differential drive robot. These trajectories are composed of straight lines and rotations in place. We show that the evolution of the position of a single landmark over time, in a local reference frame, makes it possible to track a prescribed time-optimal robot’s trajectory, based on feedback of the landmark’s position. We also show that the closed-loop system is an exponentially stable one with a nonvanishing perturbation, and that globally uniformly ultimately boundedness of the tracking errors can be achieved. The two main results of this work are: 1) Our approach leverages visual servo control type of methods with tools from optimal control for executing time-optimal trajectories in the state space based on feedback information. 2) The approach is able to work with the minimum number of landmarks–only one–this represents a necessary and sufficientcondition for landmark-based navigation. Experiments in a physical robot, a nonholonomic differential drive system equipped with an omnidirectional laser sensor, are shown, which validate the proposed theoretical modelling.  相似文献

CHANGING PERCEPTIONS OF SOCIETAL PROBLEMS AMONG SOVIET YOUTH     

Robinson  John P.; Andreyenkov  Vladimir; Slepenkov  Ivan; Kurbanov  Erjan; Davidchinkova  Lena 《Int. Journal of Public Opinion Research》1992,4(4):335-345

Dramatic changes in the perceptions of problems in the SovietUnion and in the USA are shown among samples of Soviet youthstudied over a three-year period, from 1988 to 1991. Growingdisillusionment with worsening domestic conditions was mirroredby a growing, unrealistic appreciation of life in the USA, reflectinga painful search for a new national identity.  相似文献
