چکیده :

This paper presents a novel control framework that overcomes the challenges of tractor-trailer wheeled mobile robot (TTWMRs) posture stabilization by integrating Nonlinear Model Predictive Control (NMPC) with an adaptive Particle Swarm Optimization (PSO) algorithm. Our framework addresses three critical challenges: the nonlinear dynamics of tractor-trailer systems, precise posture stabilization and parking maneuvers, and the prevention of jackknife conditions. We introduce a two-stage optimization approach where PSO first optimizes NMPC weights for positioning accuracy and then enhances energy efficiency while maintaining performance. The framework automatically adapts to different scenarios without manual tuning, making it particularly valuable for practical applications. Simulation results demonstrate exceptional performance with position errors below 1 cm and orientation errors under 0.01 radians across various parking scenarios. Compared to traditional methods, the framework significantly improves maneuverability and energy efficiency, making it an effective solution for autonomous systems in applications such as automated warehouses and industrial logistics.
