Robust position control of machine tools with a strategy of linearization by state return using fuzzy regulators

Abstract

In this paper, we show that the association of the fuzzy logic regulators with a control strategy using the linearization by return of state feedback. This is later applied to the machine tools and robot of production where the parametric variations frequently occur, offers good performances with regards to quality. The answers and its role of shock absorber of disturbances internal and external, such as the level of position or the load torque, in the presence of variations of the parameters of the machine in particular the rotor time-constant T <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">r </sub> and inertia J, which attests robustness of the command used
