Outline of Final Research Achievements

In this research project, we have tried to design observers that estimate position and velocity for sampled-data strict-feedback systems with acceleration measurement. Unfortunately, we have not found good ways to use the sampled acceleration measurement for the purpose of the observer design. We still try to design observers by applying the high-gain observer design method.
We also consider the design of reduced-order observers for sampled-data strict-feedback systems with position measurement, constant disturbances, and stable actuator dynamics. Furthermore, we have designed robust observers, high gain observers, and performance recovery of high-gain observer-based output feedback controllers for sampled-data strict-feedback systems with position measurement and model uncertainties.
