Abstract
In order to make full use of the soft robot's characteristics of flexibility and flexibility, combined with the hysteresis model, the air pressure-position hysteresis phenomenon in the soft actuator is studied, and the hysteresis compensation control method of the soft actuator is proposed. First, on the basis of the classic Prandtl-Ishlinskii (PI) model, an improved PI model and a mathematical calculation method for parameter identification are proposed; Secondly, the physical structure of the soft actuator is described, and the hysteresis data is obtained through experimental measurement; Finally, the two models used are simulated and analyzed, as well as the experimental verification of the entire system.
