Abstract

The invention relates to a dynamic compensating device for a feedback position of an encoder and a dynamic compensating method thereof. When a driver which is applied to a servo control system drives a motor to rotate at a constant speed, the driver detects the feedback position of the encoder and provides the compensation for a position error for the feedback position. Firstly, a compensation dosage of the feedback position of the encoder is calculated by a compensation dosage calculating unit, and then a position area where the compensation dosage locates is determined by a position area determining unit, and lastly the compensation dosage is corrected in different weight modes by a compensation dosage correcting unit, thereby calculating the compensation dosage through the accumulation in an iteration mode, causing an error between the feedback position of the encoder detected by the driver and an ideal position to be in a permissible range, and increasing the accuracy of the encoder for dynamically compensating the feedback position.

Description

technical field

[0001] The invention relates to a compensation device for an encoder feedback position and a dynamic compensation method thereof, in particular to a dynamic compensation device for an encoder feedback position and a dynamic compensation method thereof. Background technique

[0002] With the continuous advancement of science and technology, precise, fast, high-resolution and high-bandwidth system requirements are the goals pursued by the industry today. Speed ​​or position control is required in many products or equipment that use motors, such as optical drives, printers, X-Y platforms, robotic arms, and semiconductor process equipment...etc. If the control system can control the speed and position quite accurately and precisely, the quality and characteristics of the products or equipment produced will be better. It can be seen that the impact of precision positioning control on the development of today's technology is becoming more and more important. . ...
