Automatic regulating apparatus for controller parameters of servo driver of motor and method thereof

Abstract

The invention discloses an automatic regulating apparatus for controller parameters of a servo driver of a motor and a method thereof. The apparatus comprises an inertia identifier, a parameter initial regulator, a parameter checker, a parameter optimizer, a parameter saving and displaying device, a speed controller, a position controller, a torque controller, a PWM (Pulse-Width Modulation) generator and a coded disc. In the invention, the servo driver of an alternating current permanent magnet motor automatically configures the parameters of the position controller and the speed controller according to different rotary inertias of mechanic load, checks and further optimizes the automatically configured parameters through the parameter checker and the parameter optimizer so that the position response and the speed response of the servo driver are relatively optimal. The servo driver of the alternating current permanent magnet synchronous motor automatically regulates the control parameters according to work occasions and achieves ideal control effect. The whole process is manual participation free and completed fully by the servo motor of the alternating current permanent magnet synchronous motor.

Description

technical field [0001] The invention relates to a motor servo drive controller parameter automatic adjustment device and a method thereof, especially applied to a synchronous motor servo drive, especially designed and realized for an AC permanent magnet synchronous motor servo system. Background technique [0002] With the application of AC permanent magnet synchronous motor servo drive in different specific occasions, the size of the load moment of inertia also changes accordingly. Therefore, in order to meet the requirements for the speed and accuracy of the control effect of the servo drive, it is necessary for the user or field staff to adjust Control parameters, this parameter adjustment process is cumbersome and time-consuming, requires the adjustment personnel to have corresponding professional knowledge and experience, and it is difficult to achieve the ideal control effect. [0003] A reference document in the prior art is a patent titled "Control Constant Adjustmen...

AI Technical Summary

Problems solved by technology

[0009] The primary technical problem to be solved by the present invention is to provide a motor servo drive controller parameter automatic adjustment device and its method in order to overcome the defect that the control constants deduced by the model directly in the prior art may not be able to obtain the best control performance

[0010] Another technical problem to be solved by the present invention is that the prior art cannot guarantee that the adjusted parameter is the parameter with the best control effect. Another technical problem is that the prior art only adjusts the control constant of the speed controller. Another technical problem It is because the existing technology has not designed the function of changing the controller parameter adjustment strategy according to different user needs, and cannot properly meet the needs of users.
