Description: This paper proposes a programmable low pass
filter (LPF) to estimate stator flux for speed sensorless stator
flux orientation control of induction motors. The programmable
LPF is developed to solve the dc drift problem associated with a
pure integrator and a LPF. The pole of the programmable LPF is
located far from the origin in order to decrease the time constant
with the increasing speed. In addition, the programmable LPF
has the phase/gain compensator to estimate exactly stator flux
in a wide speed range. Consequently, the drift problem is much
improved and the stator flux is exactly estimated in the wide speed
range. The validity of the proposed programmable LPF is verified
by speed sensorless vector control of a 2.2 [kW] three-phase
induction motor. Platform: |

Description: This tutorial will guide you through the process of creating a first Zynq design using the Vivado™ Integrated Development Environment (IDE), and introduce the IP Integrator environment for the generation of a simple Zynq processor design to be implemented on the ZedBoard. The Software Development Kit (SDK) will then be used to create a simple software application which will run on the Zynq’s ARM Processing System (PS) to control the hardware that is implemented in the Programmable Logic (PL).-This tutorial will guide you through the process of creating a first Zynq design using the Vivado™ Integrated Development Environment (IDE), and introduce the IP Integrator environment for the generation of a simple Zynq processor design to be implemented on the ZedBoard.

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: |
