Abstract
Disclosed herein are an apparatus and a method for controlling a motor speed, in which an actual speed is set to be a targeted speed by considering an order of a speed increase to be meaningless no more if it is determined that a previous error and a current error are unchanged according to a result of comparing errors between the targeted speed and the actual speed upon issuing an order of the speed increase of a motor.
Claims16
An apparatus for controlling a motor speed, comprising:
- a motor;
- a targeted speed external setting unit that sets a targeted speed for the motor;
- a speed comparing unit that compares the targeted speed with an actual speed of the motor;
- an error detecting unit that detects a difference between the targeted speed and the actual speed;
- a speed storage unit that is connected with the speed comparing unit to store the targeted speed and the actual speed;
- and
- an error storage unit that is connected with the error detecting unit to store the difference between the targeted speed and the actual speed.
4 more elements
A method for controlling a motor speed, comprising:
- setting a primary targeted speed;
- detecting a difference E1 between a first targeted speed and a first actual speed that is the same speed as the first targeted speed;
- setting a secondary targeted speed;
- detecting a difference E2 between a second targeted speed and a second actual speed;
- and
- determining whether the E1 is equal to the E2.
