| Abstract |
Futher research on the models presented at EPE '87. We found simple accurate control models of 3-phase drives and simple methods to avoid ripple-(harmonic-)torques. Using the theory of multi-variable control-systems, it is possible to use seperate control circuits: one for position-(speed-)control, including torque, and one for flux-correction. Condition is to apply step-function-responses without any (oscillating) overshoot. Ripple-torque and ripple-speed disturbes often the control system. Simple matches between machine and power-electronics and adequate lay-out of the machine solves these problems. Important items have been tested. |
