Abstract: This paper deals with the mixed H2/H∞ control problem with static state feedback. The purpose of this paper is to propose an iterative method for this problem using a usable feasible direction for an H2 cost function. To do that, we derive one usable feasible direction for the H2 norm constraint firstly. Secondly an iterative method for the unconstrained H2 control problem using the direction is proposed. Next, we extend this method to that for obtaining a mixed H2/H∞ controller. Finally, the efficiency of the proposed method is shown by numerical examples.
