Abstract :
In this paper, we solve the robust H2 synthesis problem for linear fractional transformation (LFF) systems affected by white noise disturbances. Using an intermediate matrix, we develop robust and gain-scheduling control synthesis conditions in linear matrix inequality (LMI) forms. The newly proposed robust H2 control approach has been applied to several examples, and demonstrated less conservative performance than other control designs based on robust H∞ method.
