| Abstract |
The Direct Torque Control (DTC) is a modern alternative of the Field Oriented Control in practical applications. The flux and the torque of the induction machine can be controlled directly by this method. The simulation is working under the DTC concept with Switching Table strategy, but for practical implementation some new aspects should be investigated: 1. The current is controlled indirectly, requiring the implementation of the current limitation mainly during starting period. 2. The possible unstable operation in the low speed range should be avoided. 3. The simulation sets the minimal time between two switchings because the dynamic limits of the power switches must be considered. The simulation results are compared to measurements on a commercial drive with the same control. One aspect of the investigations is the dependence of the average switching frequency on different operating conditions. |
