Abstract
Saturating, soft variable-structure controls using implicit Lyapunov functions are suited for fast control of linear systems subject to input constraints. We present a simplified version of this type of control. It shows an improved performance mainly due to less restrictive stability constraints. The set of controlable plants is enlarged so this type of control can be applied to certain unstable systems for the first time. A design procedure using LMIs is presented to calculate the parameters of the controller. This procedure is used to design fast controls for two benchmark problems. Further optimisation using local noncovex optimisation leads to nearly time-optimal results.
