报告题目:Command Filter Backstepping Control of Random Nonlinear Systems
报告摘要:
The command filter backstepping method is investigated for nonlinear system disturbed by stochastic processes with strong boundedness in probability. As preliminary, the definition of semi-global noise to state practical exponential stability in probability and its Lyapunov criterion is presented. By introducing a double dynamic surface filter, practical trajectory tracking is achieved by a backstepping controller. Lyapunov stability analysis distinct from singular perturbation method is performed to the closed-loop error system. As application,the trajectory tracking of robot driven by direct current motors is achieved and a simulation on articulated manipulator is provided to demonstrate the effectiveness of the control scheme.
