Abstract: Aiming at studying on steppermotors acceleration and speed control under different constrains, the Scurve algorithm was firstly analyzed, the connections between Scurve algorithm and other algorithms used for motor control were given. After the analysis of the traditional 7sections model of Scurve, the Sbased control method for steppermotors acceleration and speed was presented, also the solutions on how to plan Scurve were discussed. Finally, the simulation results under different constraints were given. The research results show that this control method can be well used for steppermotors control under different constraints.
