Abstract EN
This paper proposes an adaptive barrier controller for servomechanisms with friction compensation.
A modified LuGre model is used to capture friction dynamics of servomechanisms.
This model is incorporated into an augmented neural network (NN) to account for the unknown nonlinearities.
Moreover, a barrier Lyapunov function (BLF) is utilized to each step in a backstepping design procedure.
Then, a novel adaptive control method is well suggested to ensure that the full-state constraints are within the given boundary.
The stability of the closed-loop control system is proved using Lyapunov stability theory.
Comparative experiments on a turntable servomechanism confirm the effectiveness of the devised control method.
