Title:
サーボ制御方法及び装置
Document Type and Number:
Japanese Patent JP5301786
Kind Code:
B2
Abstract:
The present invention relates to a method of servocontrolling an electric motor during its start-up, comprising at least one step of measuring the speed after a determined duration counting from the commencement of start-up. During a first start-up, the servocontrol system determines the deviation between the value of the measured speed and a preset value. During a second start-up, the servocontrol system modifies at least one duration parameter of the commands applied to the motor as a function of the deviation determined during the first start-up, so as to reduce this deviation in the course of this second step. Advantageously, the start-up comprises three phases making it possible to start the motor while avoiding making it too noisy. The invention also relates to an apparatus implementing the method.
