Control for Systems with Pneumatic Actuator Using Feedback Linearization

Tracking control of nonlinear pneumatic actuator systems using static state feedback linearization of the input–output map

To achieve more accurate tracking control, a control strategy for servo pneumatic systems based on the feedback linearization theory is presented. The nonlinear pneumatic actuator system is transformed into a linear system description, with a linear input–output map by regular static state feedback and state coordinate transformation. A servo tracking controller is then developed for the system...

Modified feedback linearization controller for Pneumatic System

This paper presents an approach to design a nonlinear controller for a pneumatic cylinder system for which the connection port comprises a non-negligible restriction. The pressure chamber of this system is difficult to control because the servo valve and the connection port form a double restriction. This double restriction causes a singularity in the feedback linearization controller. To avoid...

Soft Pneumatic Actuator Skin with Piezoelectric Sensors for Vibrotactile Feedback

The latest wearable technologies demand more intuitive and sophisticated interfaces for communication, sensing, and feedback closer to the body. Evidently, such interfaces require flexibility and conformity without losing their functionality even on rigid surfaces. Although there have been various research efforts in creating tactile feedback to improve various haptic interfaces and master–slav...
