Active disturbance rejection controller for smooth speed control of electric drives using adaptive generalized integrator extended state observer

HIGHLIGHTS

SUMMARY

As can see from Fig 2(a), the conventional ADRC system has the worst rejection ability for the disturbances at (a) (b) (c) (a) (b) (c) frequencies around 50 Hz, which explains why the 12th speed ripple at the speed of 300 r/min is the largest while the 60th speed ripple at the speed of 40 r/min and 60 r/min are the largest. Since the 60th speed ripple is dominant in the low-speed range while the 12th speed ripple is dominant in the highspeed range, only two GI modules are . . .
