Abstract: A design scheme of electronic CAM based on Hermite cubic spline curve was introduced. The design scheme fit the traditional three-loop control structure of servo drive controller by ensuring position curve, velocity curve and acceleration curve continuous. It improved the servo electronic cam motion control precision and performance. The design scheme can also be used in a variety of applications instead of mechanical cam.

Key words: hermite cubic spline curve, servo drive, electronic CAM( ECAM), cam application
