Control units | Expression | Control units | Expression |
|---|---|---|---|
Voltage compensator Gv(s) | \({G_v}\left( s \right)=30+5\frac{1}{s}+2\frac{{100}}{{1+100\frac{1}{s}}}\) | d-axis current compensator Gid(s) | \({G_{id}}\left( s \right)=10+\frac{1}{s}+0.5\frac{{100}}{{1+100\frac{1}{s}}}\) |
Speed compensator Gω(s) | \({G_\omega }\left( s \right)=20+5\frac{1}{s}+0.5\frac{{100}}{{1+100\frac{1}{s}}}\) | q-axis current compensator Giq(s) | \({G_{iq}}\left( s \right)=15+2\frac{1}{s}+0.5\frac{{100}}{{1+100\frac{1}{s}}}\) |
