摘要： A test rig for dynamic test assignments on internal combustion engines is equipped with a preferably electrical drive and/or loading device which is coupled to a control device for adapting and controlling setpoint values for a speed and a torque characteristic. For a test rig of this kind, in order to enable the setpoint values determined by a speed and a torque characteristic to be optimally adapted and controlled for the respective test assignment and so that they can be reproduced on the test rig in the best possible manner, the control device can be adapted in terms of adjusting the weighting of speed control to torque control.

摘要： When arrangements with a repeating working cycle such as, for example, in the case of engine test benches, are being controlled, resonances which have to be damped by the control system are often excited by the test specimen (for example an internal combustion engine) in the working range of the arrangement. The invention proposes for this purpose a control concept in which a modified actual value rist—mod is determined from a current actual value rist—akt of the control system and from a predicted imminent system-delay-free actual value on the basis of the actual value of a previous working cycle, and said modified actual value rist—mod is fed to the control system.
