Dynamic of Electrical Drive Systems with Heating Consideration

In this paper it is considered an electric drive with static torque with constant component and speed proportional component. Using the classic calculus of variations is determined the extremal control and trajectory and the overheating that ensures maximum exploitation of the system resources represented by the achievement of a maximum variation of speed in the acceleration processes N the case of electric drives working in continuous duty type, it is necessary to perform the start%up process and in the case of those electric drives working in continuous duty type with periodical change of speed, it is necessary to perform changes of speed. To estimate the heating process at the drive system acceleration, as performance number can be adopted the maximum exploitation of the system resources. Using the classic calculus of variations can be solved this optimization problem.
