Synchronized servo motors controller on Micro-precision servo press to make high precision and high formability of servo presses, as well as high productivity of general purpose mechanical presses. The mechanical servo-drive press is operated by two AC servo motors and simulation results are presented. Pressure and position are controlled though a load cell and an encoder, respectively. Here, micro-precision servo press converts torque to linear force due to ball screw. The rotational motion of the system is converted to the slide using ball screws. By the reciprocating motion of motors and ball screws, the press slide moves down and up flexibility. From these feature, two servo motors are controlled by the method which combines feedback and feed-forward control. Based on an available process model the feedback control makes the system stabilize; the feed-forward control reduce tracking error due to frictional and cogging force based on identified model of the linear motor drive system. The research tracks the errors among the input signals of motor and output signals of servo press machine, improve transient response times, reduce the steady state errors and reduce the sensitivity to load parameters. Two servo motors synchronize their speed, the encoder error of two motors get approximate about 10-300 rpm in comparison with 500 rpm _ the encoder error standard that system can accept. Servo press is its low energy consumption, only 10-20% compering with others press machine. Another advantage is a quiet and clean work environment.
