摘要： A control device is disclosed for controlling the amount of a physical quantity in accordance with a prescribed periodic function (f) for driving a controlled device (D). The control device comprises a pulse wheel device including: a magnetized member (10) fixable to a rotatable member (R) and comprising zones magnetized with opposite polarities (N, S) in predetermined angular zones, and an associated transducer (T) for generating an analog signal that varies as the angular position of the rotatable magnetized member (10) varies. The zones magnetized with opposite polarities (N, S) are arranged in such manner that at every revolution of the rotatable member a magnetic flux linked with the transducer (T) varies responsive to the angular position of the rotatable member, in a manner corresponding to the pattern of the function (f) in a period. Thereby the electric signal provided by the transducer (T) can be directly used for driving the controlled device (D).
