PSO优化的六自由度机械臂全局快速终端滑模控制
A PSO-based global fast terminal sliding mode controllerfor 6-DOF manipulators
摘要
Abstract
In this paper, we propose a global fast terminal sliding mode (GFTSM) control method based on particle swarm optimization (PSO) for the 6-DOF (degrees of freedom) manipulator control system to reduce chattering and improve response times of the system.We divided the multi-input multi-output (MIMO) 6-DOF system into six second-order subsystems, each joint designed and analyzed to overcome the singularity of control law.Further, we demonstrated the stability of our system using Lyapunov theory and optimized the control parameters based on the PSO algorithm.Our simulation results show that the optimized control method not only improves the speed and response times of the system, but also reduces the chattering, thus producing a system with good dynamics and static performance.关键词
