Practical trajectory tracking of random Lagrange systems and practical equivalence principles

摘要:The problem of trajectory tracking is considered for Lagrange systems disturbed by second moment processes. For random differential equations, the concept of local noise-to-state stability and its criterion are proposed. A full-state-feedback tracking control is designed by using vectorial backstepping method, which covers Slotine-Li controller and ``PD+'' controller as special cases. As natural extensions, adaptive control, output-feedback control and adaptive output-feedback control are presented, and three practical equivalence principles are verified. For all these cases, results of global or semi-global noise-to-state stability of closed-loop systems are obtained, and practical trajectory tracking can be achieved under a practical parameters-tuning principle.
