The optimal control signal for saturating or relay control systems is usually a complicated function of several state variables. A sub-optimal control method is to use instead a simpler signal which is a linear combination ojfunotions each of which has only one state variable as argumen,t. Persson h

## Abstract The control of systems that have sandwiched nonsmooth nonlinearities, such as a dead‐zone sandwiched between two dynamic blocks, is addressed. An adaptive inverse control scheme using a hybrid controller structure and a neural network based inverse compensator, is proposed for such syst
An output feedback controller is proposed for a class of uncertain nonlinear systems preceded by unknown backlash-like hysteresis, where the hysteresis is modeled by a differential equation. The unknown nonlinear functions are approximated by fuzzy systems based on universal approximation theorem, w
