Parameter sensitivity analyses on the discussed control methods are given. Practitioners have reported performance degradation during high speed DTC operation, including excessive torque ripple and diminished torque capability of the drive method. Asymptotic-input-output-decoupling is proposed to improve this erratic DTC performance. The results show that asymptotic decoupling compensates for erratic DTC performance with minimal control effort and controller complexity. This improvement trades off voltage headroom for torque regulation dynamics. Maximum instantaneous torque capabilities and related control strategies that can deliver high momentary forces are presented. The analyses show that by using the entire voltage headroom, in principle, up to 300% of the breakdown torque can be obtained at stall condition without saturating the magnetic circuit. An augmented vectorized volts-per-hertz control strategy is proposed and shown to provide high instantaneous torques comparable to that obtained with vector controllers.","abstract_html":"This thesis discusses various high performance induction machine control methods and provides methods for improved performance.
