Abstract

The invention discloses a Nash iteration-based distributed multi-mobile robot formation control method. The method comprises the following steps: 1) modeling is carried out on the multiple mobile robots, and a distributed discrete state space deviation model for the multiple mobile robots is obtained; 2) according to the discrete state space deviation model for the multiple mobile robots, performance indexes for a subsystem are designed; and 3) a Nash iteration-based distributed model predictive control algorithm is designed to carry out formation control on the multiple mobile robots. The distributed multi-mobile robot formation control method provided by the invention has the advantages of conciseness, easy realization and good control effects.

Description

technical field [0001] The invention relates to mobile robot control, in particular to a multi-mobile robot distributed formation control method. Background technique [0002] With the continuous expansion of the application field of multi-mobile robots, people hope that multi-mobile robots can better complete more difficult tasks; multi-mobile robots can cooperate with each other, and each robot can adjust its own state according to the operating state of other robots etc., in order to achieve the effect of coordinated control. In the collaborative control of mobile robots, the formation control of multiple mobile robots is the most basic and important goal. The so-called formation control refers to the control problem in which multiple mobile robots maintain a certain formation while meeting environmental constraints (such as avoiding obstacles). [0003] The main problems of multi-mobile robot formation control are as follows: 1) It is difficult to establish an easy-to-...
