Description: 异步电机的精确控制和速度辨识是交流传动系统中重要问题。在该仿真系统中，电机转速采用易于检测的电机定子电压和电流得到转速MRAS辨识算法来估算。由于速度辨识算法中电压模型的纯积分环节会引起的误差积累和漂移问题，采用改进积分型转子磁链估算模型来解决。-The precise control and the speed identification of AC motor are the very important issues on AC drive system.In this system, induction motor is controlled by the direct torque control, stator flux is estimated by u-n model observer that is effective in the full range of speed, motor speed is estimated by MRAS speed identification algorithm that is depended on the voltage and the current of motor stator easily detected. The modified integral rotor flux estimation model is used to solve the problem that the normal model can be affected by the error accumulation and drift of integral calculation in the voltage model of conventional speed identification algorithm.

Description: This paper proposes an exact (Kalman-like) observer for the
simultaneous state and parameter estimation in asynchronous
motors - including speed and resistant torque estimation -, as
well as a simulation study of its use under an estimate-based
speed control scheme. The simulation setup includes the model
of a PWM-controlled voltage source inverter, and the results
are quite promising. Platform: |

Description: 绝对是论坛里面最优秀的pmsm_DTC仿真了
1.按照文件中的参考文献一步一个脚印搭建的永磁同步电机直接转矩控制模型，参数也经过本人一步一步调试过了，控制效果非常好，波形非常好。
2.参考文献也在文件中，良心之作。 模块也非常清晰，房子模块化非常分明，一个模块实现一个功能，非常适合你拿去做毕业设计，也非常适合新手学习。
3.采用dq轴的磁链模型，避免了积分器的使用，因此解决了磁链估算值中直流量的积分问题。该模型绝对正确，可完美在上面构造无传感器仿真，基于卡尔曼的等等，以及预测控制仿真，占空比直接转矩等等都可以完美构建。(It's absolutely the best pmsm_DTC simulation in the forum, otherwise the other is the plagiarism, or the waveform is not right, or the part of the magnetic chain is forced to be reduced by 2, which is very inappropriate.
1., a direct torque control model of permanent magnet synchronous motor is built based on references and references. The parameters are also debugged by myself step by step. The control effect is very good, and the waveform is very good.
The 2. reference is also in the document, the masterpiece of conscience. Module is also very clear, modular house is very clear, a module to achieve a function, it is very suitable for you to do graduate design, is also very suitable for beginners to learn.
The 3. flux model of DQ axis, to avoid the use of so as to solve the integrator, flux estimation value of integral straight flow. The model is absolutely right, and it is perfect i) Platform: |
