PURPOSE: To diversely change a cam curve in a short period just with preparation of a small number of cam curve by applying the feedback control to the motor revolving position by the command value corresponding to the difference that is calculated by a subtraction means. CONSTITUTION: This control system includes a real position storage means 62 which occasionally stores the real positions Sij every time the position Sij is calculated by a real position calculation means 61, and a counter 63 which has its set count value N, varies this value N every time the position Sij is calculated by the means 61, and applies a signal to the means 62 when its count value varies by the value N to take out N pieces of stored positions Sij . Then an addition means 64 to perform the addition of STi =Nj1 ΣSij for N pieces of positions Sij which are taken out of the means 62, a subtraction means 65 which calculates the difference STi -STi -1 between the addition value STi and the addition value STi -1 which is obtained in the preceding cycle, and a position control part 100 which applies the feedback control to the motor revolving position by the command value corresponding to the difference STi -STi -1 which is obtained by the means 65 are provided. |
