Abstract
In order to realize high precision position tracking control in some dc servo system, aimed at all kinds of uncertainties, a disturbance torque compensation control tactics is put forward. In other words, friction model is approximated online by fuzzy system and identification result is taken as compensation item of control algorithm. Besides, adaptive fuzzy compensation PID algorithm is utilized. Simulation results show that compared with conventinal PID control, this control tactics can enhance dynamic performances and steady-state precision, satisfying performance requests.
