Abstract: Aimed at keeping smooth motion when mechanical part is moved at high speed, this article was compared with the traditional solutions, and was described to study the algorithm of 5th order polynomial and modsin cam curves, a proper cam curve was presented for position and velocity control. The electronic cam has been designed based on the AB motion system for high speed control. After the simulation, velocity and current were traced with cam curve control. The results indicate that with the servo running at the two cam curves, not only the acceleration and jerk are keep continuous without impact, but also performance of the system is improved to turn more stable and get a longer lifespan.

 

Key words: motion control; cam curve; electronic cam
