Abstract :
The paper presents an algorithm for computing sub-optimal l1 controllers using sequential H2 projections. As opposed to previous approaches, the algorithm does not use interpolations constraints nor attempts to solve an infinite optimization problem via finite approximation. Instead, sequential projections onto convex sets are performed to decide whether a given sub-optimal l1-norm level can be achieved or not
