| Outline of Final Research Achievements |
For nonlinear sampled-data strict-feedback systems, the design of reduced-order observers that estimate unmeasured state of the system is proposed. Their robustness and the design of proposed reduced-order observer-based output feedback semiglobally practically uniformly asymptotic stabilizing controllers is also considered under natural assumptions. The designed observers and controllers are also applied to the control problems of underactuated ships and their efficiency is illustrated by numerical simulations and experimental results. For some class of nonlinear sampled-data strict-feedback systems, the design of observer gains of the proposed reduced-order observers is also discussed by passivity of the sampled-data systems.
