Implementation and Evaluation of a Stator and Rotor Flux Linkage-Based Dead-Beat, Direct Torque Control of Induction Machines at the Operational Voltage Limits

Dead-beat, direct torque (and flux) control of an induction machine is experimentally achieved at a 10 kHz sampling frequency. The inverse solution utilized lends itself to a very insightful graphical representation. This allows for an objective experimental evaluation of voltage vector choices in the operational voltage limits. The parameter sensitivity of the control algorithm is also investigated.
