摘要：
Digital redesign for observer-based output-feedback tracking controller with time-varying references is developed. The improvements have been done by more precisely approximating the reference and considering the state matching of the estimation error in a plant dynamics for a large sampling period, and by using the delta-operated discrete-time modelling for an extremely small sampling period.
