| Abstract |
This paper describes an AC-servo drive which can be controlled in different speed and position control modes. The drive is adapted to a cost efficient modified standard induction motor with an integrated encoder. The current vector control algorithm is derived from the steady-state solution of the well-known dq-dynamic model. This control method has proven to be very robust to changes in motor temperature. A signal processor is used to run all the control algorithms, and a μ-controller is used for parameter setting and bus control. An ASIC has been developed for encoder signal processing. The results prove that servo performance have been achieved. |
