Embodiment approach 1

[0029] use below Figure 1-Figure 4 The actuator system 1 according to Embodiment 1 of the present invention will be described.

[0030] The transmission system involved in this embodiment has the function of automatic adjustment of control parameters, such as figure 1 As shown, it includes L (natural number) sets of electric actuators 100 , control devices 200 and adjustment devices 300 . and figure 1 Only one electric drive 100 is shown.

[0031] The control device 200 cooperates with the adjustment device 300 to work as the control parameter adjustment device of the present invention.

[0032] The electric actuator 100 operates according to a control signal from the control device 200 to drive the load 400 . The electric actuator 100 includes a power generation unit 110 , a power transmission unit 120 , and a detection unit 130 .

[0033] The power generation unit 110 is a component that converts electric power supplied from a power source into mechanical power. The p...

Embodiment approach 2

[0090] Next, an actuator system 1a according to Embodiment 2 of the present invention will be described. The actuator system 1a related to Embodiment 2 is as follows: Figure 5 What is shown is different from Embodiment 1 in that the adjustment device 300a is further provided with a history information DB 340 that stores the control parameters calculated in the control parameter adjustment processing. In addition, in the following description, the same components of the actuator system 1a according to the second embodiment and the actuator system 1 according to the above-mentioned first embodiment are assigned the same reference numerals.

[0091] In the history information DB 340 , various values ​​calculated by the adjustment device 330 a in the second embodiment during the control parameter adjustment processing are stored in association with the processing date and time when the processing was performed. Specifically, as Figure 6 As shown, the historical information DB ...

Abstract

The adjusting device (300) comprising an electric actuator information DB (310), which can be used to store the regulation rule information of the regulation rule of the control parameters adjusted by the electric actuator (100); a control part (330) used for adjusting the control parameters of the electric actuator (100). The control part (330) can acquire regulation rules, which are input by the interface part (320) and identified by the electric actuator, from the electric actuator information DB(310). According to the equivalent inertia moment of the electric actuator (100) and the acquired regulation rule information, the control parameter of the electric actuator (100) can be calculated, and the control parameters stored in the control device (200) an be updated.

Description

technical field [0001] The invention relates to a control parameter adjustment device, a transmission system and a control parameter adjustment method for adjusting control parameters for controlling an actuator. Background technique [0002] Patent Document 1 discloses an example of a method of adjusting control parameters such as gains used in feedback control of a motor. In this method, for example, the stored setting value is multiplied by α. [0003] [Prior Art Literature] [0004] 【Patent Literature】 [0005] [Patent Document 1] JP-A-2009-183083 Contents of the invention [0006] 【Problems to be solved by the invention】 [0007] The motor is connected to various power transmission units such as ball screws. Therefore, generally speaking, in the driving circuit of the driving motor, the control parameters can be set in a wider range. Therefore, in an actuator equipped with a motor and a power transmission unit, if the control parameters are adjusted according to...
