Due to its theoretically fast dynamic response with unlimited bandwidth for direct switch-driven-based induction machines, the finite control set predictive current control (FCS-PCC) method has been verified to be an effective solution in recent years. However, dynamic limitations of the outer speed PI controller exist, especially with high-order time-varying disturbances. In addition, hardware cost can be reduced. Using the universal proportional integral observer (UPIO) method, a robust deadbeat-like encoderless-based FCS-PCC control scheme is investigated for induction machine systems in this paper. The encoder is avoided using the proposed sensorless method. In addition, the system response and disturbance attenuation are enhanced in presence of time-varying unknown load torque and uncertainties. The squared norm is adopted for the cost function design to ensure system stability. Experimental results illustrate that it has good performance such as fast dynamics, good low-speed steady-state accuracy, and robustness.

用于具有高阶干扰补偿的基于逆变器的感应电机系统的鲁棒无传感器 FCS-PCC 控制

有限控制集预测电流控制（FCS-PCC）方法由于其理论上具有无限带宽的理论快速动态响应，适用于直接开关驱动的感应电机，近年来已被证实是一种有效的解决方案。然而，外部速度 PI 控制器存在动态限制，尤其是高阶时变干扰。此外，可以降低硬件成本。使用通用比例积分观测器 (UPIO) 方法，本文研究了一种鲁棒的类似无编码器的 FCS-PCC 控制方案，用于感应电机系统。使用建议的无传感器方法避免了编码器。此外，在存在时变未知负载转矩和不确定性的情况下，系统响应和干扰衰减得到增强。代价函数设计采用平方范数，保证系统稳定性。实验结果表明，它具有良好的性能，如快速动态、良好的低速稳态精度和鲁棒性。
