Abstract
In recent years, interests have emerged for application of MEMS for optical switching in telecommunications industry. Real time robust control of a nonlinear MEMS optical switch using quantitative feedback theory (QFT) method in switching operation is considered in the present work. Nonlinear system rendered into linear configuration by employing system identification techniques to exploit applications of QFT to envisage robust stabilization, tracking specification and perturbation attenuation. Simulation studies are conducted to show the efficiency of the proposed robust scheme as well.Keywords
