“…In many cases where high control performance is required, these simplified models may not be accurate enough to meet the requirements. A linear third-order autoregressive moving average with an exogenous-variable (ARMAX) model describing the dynamics of the PUMA 762 robot has been developed by Dai et al [8]. However, from the adaptive control point of view, a parametric model accurately describing the dynamics of the whole RDG process, including the robot and the grinding process, is still required.…”
