A new adaptive super-twisting integral terminal sliding mode control strategy is proposed for uncertain n-degree of freedom rigid manipulator dynamics to realize trajectory tracking control. Firstly
a new integral terminal sliding mode surface design is presented
and based on the proposed improved variable exponential reaching law scheme
an adaptive sliding mode variable structure controller is designed to suppress the unknown uncertainties and external disturbance of the system effectively
further ensuring the system to reach the sliding mode surface quickly and reducing the system chattering. Secondly
the convergence of the manipulator error system is analyzed by constructing an appropriate Lyapunov function. Finally
the effectiveness of the proposed control method is verified by simulation experiments with a two-degree of freedom manipulator plant model.
