A Controller Switching between Twisting and Linear Algorithms for an Electropneumatic Actuator

International audienceThis paper presents a new control strategy for a perturbed electropneumatic actuator. This new control law is evolving between a robust second order sliding mode controller (based on twisting algorithm) and a linear one. This objective is to ensure high accuracy tracking and low energy consumption, in spite of perturbations and uncertainties. This new control solution is evaluated on an experimental setup
