High-Performance MotionControl ofLinear MotorDrives

This paperpreselnts ahigh-perfomance lineardrive colntrol featuring encoder signal correction, oscillation damping andanadvanced feedforward control forfriction, speed aldacceleration toreduce the dynamic trajectory errors.These measuresandtools aiming atcontrol optimization areinvestigated conceriing their perfonmance andbenefits withlinear drive systemis. Major costs can bereduced by using magneto-resistive orhall effect based sensors.Different methods fordeterming thecommutation angleallow toreplace theabsolute position encoders byincremental encoders.Specific alalysis and commissioning tools allow aneasyhandling oftheadvanced features.
