Abstract
A method and apparatus for controlling the load of a dynamometer. While the dynamometer is driven or coasted with a plurality of armature currents properly selected between -100% and +100% of the rated armature current, each time value it takes the dynamometer speed to vary from one preset speed level to the next preset speed level is measured and converted into a load value which is then stored together with the corresponding dynamometer speed and armature current values. Proper load, speed and current values are read out in accordance with a given targeted load and dynamometer speed for calculation of a targeted control current corresponding to the targeted control load using interpolation.
