Linear electric motors in combination with appropriate systems of power electronics and control offer realisation of servo drives with excellent dynamic performance and a high degree of positioning accuracy. This thesis describes the methods used to tune the speed and position PID controllers of a drive system based upon a synchronous linear motor with rare-earth permanent magnets.
Within the span of this thesis we upgraded the system with a newer variable-frequency drive and motion controller. Basic operation was first established by entering the relevant parameters and settings into the variable-frequency drive. Then an applicable computer model of the speed and position control loops was built, with which we optimized the settings of the PID controller. Best control loop performance was obtained by numerically minimizing the ITAE criteria in the computer model.
