STABILIZATION OF SLOW-MOVING ELECTRICAL DRIVES USING FUZZY-LOGIC

The paper describes fuzzy logic application in control systems for slo w-moving, positional and servo drives with a low-frequency non-linear moving part which makes it impossible to stabilize the motion correctl y using traditional correction means. The control system together with a fuzzy regulator is shown to eliminate oscillations of the drive wor king element while conserving a high accuracy of positioning and servo ability. The paper gives the procedure for constructing a fuzzy regul ator algorithm which provides high dynamic properties and accuracy of the electrical drives selected.
