Research of nonlinear position error of electric cylinder

Aiming at position error of linear motion of a type of electric cylinder,a composite patterns error compensation method of "least squares linear fitting compensation,nonlinear adaptive fuzzy PID of nonlinear error compensation" is proposed,specially analyze on nonlinear error compensation and mathematical model for electric cylinder test system is established and simulated to prove the reliability of the adaptive fuzzy PID compensation.It is combined with the experiment to verify and it is proved that the method is feasible and ideal effect is obtained.
