Popis: Design and verification of two energy saving position control algorithms for drives loaded with combined constant and linear friction and load torques is main contribution of this paper. To decrease energy demands energy near-optimal control law based on copper losses minimization is compared with a control law based on symmetrical trapezoidal speed-time profile. Both algorithms respects prescribed maneuver time and have prescribed acceleration to achieve the demanded position. Overall control system exploits principles of vector control and forced dynamics control. A zero dynamic lag pre-compensator is included for precise tracking of prescribed state variables. Energy demands of both control algorithms are verified and compared by simulation, results of which confirmed possibility to achieve energy savings for pre-planned rest to rest maneuver.
