High Performance Position Control of Double Sided Air Core Linear Brushless DC Motor

Abstract

Double-Sided Air Core Linear Brushless DC motors widely used in the industry where longitude motion is needed. In terms of efficiency, high speed and acceleration, long life, Stiffness, few moving parts, precise positioning and no transmission components, and so on have many advantages. In this paper position control of a Double Sided Air Core Linear BLDC motor is studied by two methods, first of all the classical PID control method is applied to the system and then Fuzzy-PID control method is investigated on system. The motor specifications and technical features of it are derived and presented. The simulation and the motor model including the control algorithm is built by using of Simulink and is investigated. Finally, to validate simulation result, designed controllers are applied to the Double-Sided Air Core Linear Brushless DC Motor practically. The experimental test results validate simulation result and the accuracy of the both control method and their dynamic performances are compared with each other.
