Radial basis function neural network based second-order sliding mode control for robotic manipulator

Abstract: An adaptive second-order sliding mode control method based on RBF neural network is proposed for n-DOF robotic manipulators in the presence of external disturbances. First, RBF neural network is used to approximate the model information. Second, by using adaptive technology to compensate the uncertainty, whose prior knowledge about upper bound is not required. In addition, since the proposed control scheme is continuous, the chattering phenomenon is almost completely eliminated. Finally, the stability and fini… Show more

“…Lewis et al (1996) designed an RBF neural network adaptive controller that used the RBF neural network to approximate the uncertain terms of the manipulator model so that SMC could get rid of the dependence on the dynamic model information and realize joint trajectory tracking control. Chen et al (2019Chen et al ( , 2022 selected different neural network structures to improve SMC and enhance the dynamic performance of the system to varying degrees. Even so, the accuracy of the whole system is inevitably affected by the errors of the neural network.…”
