无速度传感器直接转矩控制方案的设计与实现

Design and Implement of Speed Sensorless Direct Torque Control Scheme

将一种全阶的磁链观测器运用到直接转矩控制系统当中,并在此基础上辨识出电机转速。其数字化实现基于双DSP来完成。仿真和实验结果验证了方案的可行性。

A full-order flux observer is used in the direct torque control systemand then the rotor speed is estimated. This approach has been implemented on a dual DSP control system. Simulation and experimental results indicate that the proposed scheme is effective.
