blockSpeedDependentTorque
Load torque dependent on speed
Extends from Modelica.Blocks.Interfaces.SISO (Single Input Single Output continuous control block).
Information
Model of a speed dependent load torque. It is zero for time < startTime, i.e. it can be switched on at startTime producing a torque step.
Speed dependency of torque can be choosen from:
- Unidirectional ... same direction of constant torque in both directions of rotation
- Constant ... constant torque with linear regularization around zero speed
- Linear ... linearly speed dependent torque
- Quadratic ... quadratic speed dependent torque
