“…This will bring great difficulties to the design of its controller (Ajwad et al, 2018; Han et al, 2021; He et al, 2015; Hong et al, 2020; Liu et al, 2019). It has been noted (Baumann et al, 2018) that the radial basis function (RBF) neural network has good generalization ability, and can effectively improve the performance of the controller when the system has a large uncertainty (Baumann et al, 2018; Cheng and Liu, 2020; Gambuzza et al, 2017; Gao et al, 2018; Jin et al, 2021; Kvatinsky et al, 2012; Rani and Kumar, 2019; Wang et al, 2019). However, with the continuous advancement of technology, the robotic manipulator control is required to become more and more intelligent.…”
