The Research of Direct Torque Control Based on Full-dimensional State Observer

摘要：

To overcome integrator initial value, error accumulation and DC offset of pure integration, there proposed a permanent magnet synchronous motor stator flux observation method based on full-dimensional state observer. It uses the stator flux as state vector structural system state equation, the current as the output vector structural system output equation. And it configures the observer poles proportional to the motor model poles and use robust pole assignment algorithm in Matlab for observer gain matrix calculation. Experiments show that the fulldimensional observer on the stator flux observed has higher accuracy. The direct torque control system has better performance.
