Embodiment Construction
[0153] In order to describe the present invention more specifically, the technical solutions of the present invention and related working principles are described in detail below.
[0154] Such as figure 1 As shown, an ADRC parameter automatic adjustment system for permanent magnet synchronous motor vector control, including ADRC parameter selection index calculation module (COM).
[0155] COM gets the speed error (e 1 ), Speed Active Disturbance Rejection Controller (ADRC 1 ) output signal (u 1 ), d-axis current error (e 2 ), d-axis current active disturbance rejection controller (ADRC 2 ) output signal (u 2 ), q-axis current error (e 3 ), q-axis current active disturbance rejection controller (ADRC 3 ) output signal (u 3 ); output ADRC parameter selection index H; ADRC parameter selection index calculation module (COM) working state is controlled by drive signal;
[0156] COM calculates the acquired signals, and obtains a comprehensive evaluation index H that can ...
