Abstract :
The problem of synthesis of l1 optimal robust controller for SISO plant under coprime factor perturbations and bounded external disturbance is considered. A geometric interpretation of l1 optimal robust controller, standard l1 optimal controller, and two other optimal robust controllers is presented. The existence of l1 optimal robust linear controller is proved and an algorithm for approximate solution of the problem is proposed. The algorithm is reduced to approximate solution of finite family of standard l1 optimization problems
