Abstract
In this paper, we provide a further result on the output feedback control problem of nonlinear systems with unknown measurement sensitivity studied in [2]. We provide a gain-scaling output feedback controller and a process of determining the allowed measurement sensitivity. As a result, we show that more nonlinearity and measurement sensitivity can be treated by our method. Various examples are presented to illustrate the improved features of our control method.
