Structured control of affine linear parameter varying systems

This paper presents a new procedure to design structured controllers for discrete-time affine linear parameter-varying systems (A-LPV). The class of control structures includes decentralized of any order, fixed-order output feedback, simultaneous plant-control design, among others. A parameter-varying non-convex condition for an upper bound on the induced L
