An improved deadbeat predictive current control for induction motor drives

Deadbeat predictive current control (DPCC) has been widely studied in induction motor drives due to its simple concept, quick response and excellent steady-state performance. However, conventional DPCC uses a lot of parameters predict voltage. Therefore, the performance is affected by accuracy controller. The will severely deteriorate when used controller deviate greatly from their actual values. To improve parameter robustness DPCC, this paper proposes robust (RDPCC), which utilizes error between measured currents predicted compensate for influence machine mismatches. proposed method compared with experimental results confirm strong against mismatch.
