Fc. Sun et al., Stable neuro-adaptive control for robots with the upper bound estimation on the neural approximation errors, J INTEL ROB, 26(1), 1999, pp. 91-100
An indirect adaptive control approach is developed in this paper for robots
with unknown nonlinear dynamics using neural networks (NNs). A key propert
y of the proposed approach is that the actual joint angle values in the con
trol law are replaced by the desired joint angles, angle velocities and acc
elerators, and the bound on the NN reconstruction errors is assumed to be u
nknown. Main theoretical results for designing such a neuro-controller are
given, and the control performance of the proposed controller is verified w
ith simulation studies.
