Abstract
Various aspects of the present disclosure are directed to, for example, methods of controlling a rotational speed of a maching. In one example embodiment, the method includes the steps of: generating a rotational speed reference variable for a controller from a rotational speed setpoint value; determining an adapted rotational speed setpoint value which considers a rotation angle actual value and a rotation angle setpoint value determined on the basis of the rotational speed setpoint value; and switching the rotational speed reference variable between the rotational speed setpoint value and the adapted rotational speed setpoint value as a function of the rotational speed.

A method for controlling a rotational speed of a load machine on a test bench, the load machine being connected to a test object via a shaft, including the following steps:
- measuring the rotational speed by means of a sensor arrangement, the measured rotational speed being fed back to a controller as a rotational speed feedback variable;
- determining, in the controller, a deviation of the rotational speed feedback variable from a rotational speed reference variable;
- supplying the deviation of the rotational speed feedback variable as a control difference to a control element which generates a manipulated variable for the load machine in accordance with a defined control strategy;
- generating the rotational speed reference variable for the controller from a rotational speed setpoint value;
- determining an adapted rotational speed setpoint value which considers a rotation angle actual value and a rotation angle setpoint value determined on the basis of the rotational speed setpoint value;
- switching the rotational speed reference variable between the rotational speed setpoint value and the adapted rotational speed setpoint value as a function of the rotational speed feedback variable to control the rotational speed of the load machine.
