Test bench and method for carrying out a test run on a test bench

A test bench for carrying out a test run, the test bench comprising:

• a load machine configured to be coupled to a test object;
• a torque controller configured to adjust an actual torque (T_ist) of the load machine;
• a test bench automation unit configured to specify a target torque (T_soll) for the torque controller according to the test run;
• a test object controller configured to specify a test object control variable (SW) for the test object;
• a rotational speed determination unit configured for determining an actual rotational speed (n) of the load machine;
• at least one comparison unit configured to determine at least one deviation (a, a1, a2) of at least one attribute of the actual rotational speed (n) from at least one threshold value (G);
• at least one correction unit configured to determine, based on the at least one deviation (a, a1, a2), at least one additive torque correction value (Tk) and superimpose it on the target torque (T_soll).
