ROBUST MOTION CONTROL FOR LINEAR MOTOR DRIVES

摘要

In this paper several control strategies were developed for motion control of linear motors. The results show that Sliding Mode Control (SMC) in combination with Minimum Time Path Optimization (MTPO) results in good control performance particularly in the presence of load disturbances. The structural dynamics of the linear motor represent important constraints for the speed and acceleration of the motor and for appropriate selection of controllers' parameters. These dynamics must also be considered when locating the position of the feedback device.
