“…Another important aspect is that, for strictly positive values of β , ξ ( t ) can be seen as a smoothed approximation of α ( t ). Furthermore, the bigger β , the smoother ξ ( t ), as shown in Ferreira et al [25].…”

This paper presents new convex conditions to design robust and linear parameter varying (LPV) gains for continuous time-varying systems subject to saturating actuator and energy bounded disturbances. The input-to-state stability conditions are used to design controllers ensuring the minimization of the  2 -gain between the disturbance input and the controlled output. Furthermore, optimization procedures to maximize the estimate of the region of attraction, and the bound to the control signal as well, are formulated. The efficacy of the proposed methods is illustrated with numerical examples, including a reference tracking problem, where realistic simulations are performed.
