ABSTRACT:
A servo control apparatus for controlling a rotation speed of a motor such as a capstan motor or a drum motor for a video tape recorder. In the servo control apparats, a control value generating unit generates a control value on the basis of a difference between the rotation speed of the motor detected by a rotation speed detecting unit and a desired value of the rotation speed. When a deviation value representing a difference between the control value generated by the control value generating unit and an ideal control value representing an ideal value of the control value is constant for a predetermined period of time, an error state monitoring unit outputs the deviation value. An adding unit adds the control value generated by the control value generating unit with the deviation value to obtain a result of addition, and a drive voltage generating unit drives the motor by a drive voltage according to the result of addition from the adding unit.
