Energy Near-Optimal Control Strategies for Industrial and Traction Drives with a.c. Motors

Table 1

Summary of total energy consumption for chosen load torque components.

Torque component	Energy optimal control	Energy near-optimal control
Constant  Nm, ,	= 105.936 J	= 106.433 J
Viscous ,  Nms,	= 226.813 J	= 229.5273 J
Quadratic , ,  Nms^2	= 475.604 J	= 482.739 J

Rem.: individual torque coefficients , , and were chosen in such a way that they create load torque of 10 Nm for a given cruising speed.
