This paper presents a study on the problem of designing non-fragile H-infinity controllers with sparse structures for linear continuous-time systems. A new algorithm is proposed to define and further design sparse structured controllers. Firstly, sparse structures are specified from a given fully parameterized H-infinity controller. Then, a three-step design procedure for non-fragile dynamic output feedback H-infinity controllers with the sparse structures is provided. The resulting designs guarantee that the closed-loop system is asymptotically stable and the H-infinity performance from the disturbance to the regulated output is less than a prescribed level. A numerical example is given to illustrate the design methods.
