Formation Control of Multi-Robot using Virtual Structures with a Linear Algebra Approach

Abstract

The separation bearing controller (SBC) and separation-separation controller (SSC) approaches can be used to maintain multi-robot formation, while the Computed Torque Control (CTC) method is used to solve the dynamic problems of the robot. However, the SBC and SSC approaches combined with CTC cannot maintain multi-robot formation, if the leader or follower is disturbed. In this paper, the virtual structure method and the linear algebra approach added to the CTC method are used to maintain the triangular robot formation to follow the given trajectory. The simulation results show that the proposed control system design of multi-robots capable of following the trajectory and can maintain multi-robot formation with/without disturbance and noise.

Formation Control of Multiple Mobile Robots Based on Fuzzy Adaptive Sliding Mode Control

“…The stable and reliable formation is an important condition for multi-mobile-robot cooperation. Now, the multi-robot formation methods include the leader-follower formation method [1][2][3] , virtual structure formation method [4][5] , behavior-based method [6] , particle swarm optimization algorithm [7] , gray wolf optimization algorithm, and other intelligent algorithms. Zhang F F et al [8] applied a velocity compensation algorithm based on position information to the leader-follower formation, which improved the formation efficiency.…”
