| الوصف: | Nonlinear extension of the integral part of PID feedback control is proposed for the perturbed second-order systems. For the matched constant perturbations, the global asymptotic stability is shown, and for Lipschitz perturbations an ultimately bounded output error is guaranteed. The second-order system plants can also be expanded by an additional (parasitic) actuator dynamics with low-pass characteristics. The proposed nonlinear control is proven to outperform its linear (PID) benchmarking counterpart during the settling phase, i.e. at convergence of the residual output error. An experimental case study of the second-order system with an additional actuator dynamics and considerable perturbation is demonstrated to confirm and benchmark the control performance. Comment: 6 pages, 9 figures |
