In this paper, we consider a suboptimal control problem based on the input-output data through the LFT representation. First we describe the suboptimal control problem in a general setting via the LFT. Then we solve the problem via numerical optimization, where the relation between the design parameters and the cost function plays a key role. For this equation, we discuss how to solve the optimization problem. Finally, we give numerical examples of controller design to demonstrate its effectiveness.
