Design method of single-delay controller for multiple mobile robots based on lambert W function

Abstract

The present invention provides a multi-mobile rotor single time-delay controller design method based on a Lambert W function. The method comprises the following steps: 1) obtaining a model that a single mobile rotor is first-order integral according to the Lagrange method; 2) establishing a single time-delay controller of a multi-mobile robot system according to the model parameters; 3) selecting appropriate time-delay parameters and solving the range of the single time-delay controller proportion parameters which allow the mobile rotor to be stable based on the Lambert W function; 4) inputting the model parameters of the mobile robot into a calculation unit of the time-delay control parameters, and inputting the control parameters to a monitoring module for executing a presetting control program; and 5) applying the single time-delay controller stabilized by the presetting system to each mobile rotor to perform cooperation control of the stable mobile robot. The speed difference between the mobile robots is regulated through the single time-delay controller program to allow the whole system to be consistent and complete the cooperation control.

Description

Technical field [0001] The invention relates to a coordinated control method of a multi-mobile robot system. For the multi-mobile robot system, a control parameter that can stabilize the system is selected, and a single time delay controller is designed, thereby improving the consistency of the system. Background technique [0002] The multi-mobile robot system is a very important branch in the field of distributed artificial intelligence systems. Multiple mobile robot systems have become the main research object in distributed artificial intelligence research in the late 1980s. The main purpose of studying the multi-mobile robot system is to carry out distributed collaborative control between multiple mobile robots with relatively simple functions, complete complex tasks, and provide reliable support for operations in extreme environments. [0003] The development and research of mobile robot control systems have received more and more attention and attention. On the one hand, t...

AI Technical Summary

Problems solved by technology

It is impossible to make the entire multi-mobile robot system meet certain performance index requirements, and it is also difficult to flexibly achieve different global control objectives

Moreover, the time delay is regarded as an unfavorable factor in the design of the control system, which causes the system to produce periodic oscillations, divergence phenomena, etc.
