Abstract

PURPOSE:To further enhance the automatic compensating accuracy of the lost load of a dinamometer device by always detecting the varying causes of the lost load so that the variations in the lost load are automatically compensated. CONSTITUTION:The temperature and pressure at the respective portions, which cause the lost load to vary, are always detected. If the variations exceed the allowable value, a change-over circuit 40 generates its output thereby to effect an automatic change to the drive or absorption at a preset current of the motor. Similarly to the detection, in which automatic control is performed upon the temperature and pressure within a preset range, the calculations are performed in a calculation memory unit 22, and the detected values are memorized in a preset address. These values are compared with the memorized detected values so that either of the previous detected values and the target load to be controlled are compensated. Thus, it is possible to further enhance the automatic compensating accuracy.
