In this article, a novel sliding mode adaptation mechanism of a model reference adaptive system speed estimator and a modified sliding mode speed controller are proposed to replace the proportional-integral controller used in the adaptation mechanism of the model reference adaptive system and the proportional-integral speed controller, respectively. The suggested control strategy is designed by sensorless direct torque control with space vector modulation based on a sliding mode speed controller and a model reference adaptive system sliding mode speed estimator. The contribution of this work is the development of one control law based on a modified nonlinear component to overcome the first-order sliding mode control limitations, such as the chattering phenomenon. The performance of the suggested controller-based direct torque control with space vector modulation is verified by digital simulation with different operation conditions, like the abrupt variations in the load torque and the reference speed, using the MATLAB/SIMULINK environment. In fact, such simulation results are experimentally checked utilizing a dSPACE-1104.

基于非线性积分滑模控制器的感应电机驱动无传感器直接转矩控制：实验验证

本文提出了一种新的模型参考自适应系统速度估计器的滑模自适应机制和一种改进的滑模速度控制器来代替模型参考自适应系统自适应机制中使用的比例积分控制器和比例积分控制器。速度控制器，分别。建议的控制策略是通过基于滑模速度控制器和模型参考自适应系统滑模速度估计器的空间矢量调制无传感器直接转矩控制设计的。这项工作的贡献是开发了一种基于修正非线性组件的控制律，以克服一阶滑模控制的局限性，例如颤振现象。建议的基于控制器的空间矢量调制直接转矩控制的性能通过使用 MATLAB/SIMULINK 环境在不同操作条件下（如负载转矩和参考速度的突然变化）的数字仿真进行验证。事实上，此类模拟结果是使用 dSPACE-1104 进行实验检查的。
