In ordinal regression, a score function and threshold values are sought to classify a set of objects into a set of ranked classes. Classifying an individual in a class with higher (respectively lower) rank than its actual rank is called an upgrading (respectively downgrading) error. Since...

In the conventional H∞ optimal output feedback control design, the order of the controller is higher than that of the plant. Thus, it is not easy to implement H∞ optimal control in real world engineering problems. This paper tries to bridge the gap between the theoretical H∞ control and...
