PURPOSE:To prevent the occurrence of hunting in control, by compensating a feedback fundamental controlled variable to be determined on the basis of a positional deviation between an actual position and a desired position of the controlled system of a throttle valve or the like with a compensation value based on a position variation in the controlled system. CONSTITUTION:In case of a device which drives and controls a control system 1 of a throttle valve or the like with a driving device 2, there is provided with a judging device 5 judging a driving direction of the controlled system 1 from a deviation in each output of a position detecting device 3 detecting an actual position of the controlled system 1 and a desired position detting device 4. And, also there is provided with a detting device 6 setting a fundamental controlled variable with the driving device 2 in response to the said deviation. In addition there is provided with a detecting device 7 detecting a position variation of the controlled system 1 on the basis of output of the position detecting device 3. And, according to a comparing result between the position variation and the specified variation, a compensation value is determined by a setting device 8, and in conformity with this compensation value, the said fundamental controlled variable is compensated by a driving signal generating device 9 and the driving device 2 is controlled.
