- Abstract
- This paper deals with the torque control of polyphase segment surface-mounted-permanent-magnet synchronous machines. First, we introduce a Lagrangian formulation for computing the optimal sinusoidal currents allowing to develop a given torque, both in normal operation mode and in fault operation mode (loss of one phase). Then, we present a torque control architecture allowing to switch from normal to fault operation mode with a minimum reconfiguration of the controller. All the theoretical results are validated by simulation and experiments on a test bench.
