“…However, an explicit solution to a MPC problem, which was obtained offline, applies this control scheme only for a linear time-invariable (LTI) system or a piecewise affine (PWA) system [14]. Mohammadzaman et al [15] showed the effectiveness of a generalized predictive control (GPC) algorithm for robust control in the presence of backlash non-linearity without a priori knowledge of upper and lower bounds of backlash. In addition, backlash compensation using neural network and fuzzy logic have been used in feedback control systems [16,17].…”

Backlash in servo mechanisms causes a severe deterioration in system performance.To reduce the influence of backlash on the system, a backstepping integral adaptive control is proposed. A dynamic model of a servo mechanism with backlash, considering equivalent stiffness and damping, is established. The control design is achieved by introducing parameter adaptation with a backstepping technique that ensures the convergence of parameter estimation and global stability of the adaptive system. Simulation and experimental results show that the system's tracking accuracy and servo bandwidth are significantly improved and increased. More importantly, the impact and oscillation are evidently reduced while reversing, compared with conventional proportional-integral-derivative control.
