Mode Selecting Control of Interior Permanent Magnet Synchronous Motor for Full Speed Range Operation
The paper presents a new method for mode selecting which includes constant torque mode and flux-weakening mode. The proposed method modifies the working modes not by LUT (look-up table), but by the size of T0. Attractive features of this state transition technique include no dependency on the machine parameters, the least calculated quantities, making full use of the source voltage of the battery, and smooth and fast transition into and out of the flux-weakening mode. Simulation results at various operating conditions are presented to verify the feasibility of the proposed mode transition scheme.
