Information

It shows that the generated torque follows the normalised torque request as long as it does not overcome the allowed maximum. Actual torque will be this request times the maximum value that, in turn, is the minimum between tauMax and powerMax/w (while w is the rotational speed)

It shows also the effects of efficiency on the DC power.

First suggested group of plots: on the same axis oneFlange.torque.tau, and tauRef vertically aligned with the previous oneFlange.limTau.state and oneFlange.limitingTorque. In these plots it can be seen that:

·       during the first 10 seconds the generated torque oneFlange.torque.tau, is 100Nm, as requested from the input. The maximum torque that can be generated is not limited by the nor the torque limit nor the power limit. Reached speed is 54 rad/s.

·       between t=10 and 14.3 s the generated torque continues to follow the input signal, without hitting limits (limitingTorque=0 and state=0)

·       at t=14.3s the maxTorque limit is reached: limitingTorque =1, state remains 0 because we still are below wBase

·       at t=15.2s we reach the maximun power limit, state becomes 2.

·       Starting from 15.2s, the delivered power is reduced because we are in the max speed limiting zone.

Second suggested group of plots: 

This behaviour can be well undertood by means of a parametric plot, putting speed on the abscissa, tauRef, oneFlange.torque, and loadTorque.flange.tau on the ordinate.

To analyse this complex plot well, a plot of inertia.w versus time is helpful.

Further suggested plots: Once the first plot is anaysed, the user might want to have an idea of the mechanical and electrical powers: these are seen putting in the same plot powMech.power and powElec.power. The trend of efficiency could be also of interest (variable oneFlange.toElePow1.toEff.y)
