Virtual-Design-Model-Based Pressure-Tracking Control of High-Dynamic Pneumatic Valves Using a Sliding Mode Controller Combined with a Proportional-Integral-Derivative Scheme

Abstract

This paper deals with the issue of pneumatic pressure-tracking control based on a virtual design model of high-dynamic valves. As a fundamental step prior to controller design, a virtual valve model is developed by defining the required parameters through analysing geometrical and material data. For validation of the virtual model, the open-loop performances of subsystems are compared with experimental results. A sliding-mode controller combining a proportional-integral-derivative scheme is developed for compensation of inherent non-linearities and thus a significant reduction in tracking error is achieved for pressure-tracking control applications.
