Abstract

Deadzone and backlash are two common non-linearities in physical systems. This paper presents a novel approach to compensate for the effects generated by deadzone and saturation, or backlash and saturation, acting in series on a system's input. It takes advantage of the idea of inverting the deadzone or backlash to cancel its effects. It is shown that the final setting corresponds to that of a saturation. Hence anti-windup is proposed as an effective control strategy.
