Improvement of the electronic line-shafting

Electronic (virtual) line shaft has shown its feasibilities and improvement in multimotor arrangements where high-performance applications that are able to achieve precise control of position, speed, acceleration, and deceleration are required. Several studies have been done in order to increase its performance and productivity. However the relative angle between multi axes and a procedure to avoid the virtual line has not been discussed. Therefore, this paper develops a commission procedure to avoid the virtual line in the classical electronic line shaft and it presents a novel array, which lets to reach an equal speed and zero position error between axis during the startup, shutdown conditions and under load impacts on any motor.
