Abstract

In this paper, a novel cascaded predictive control strategy, endowed with the merits of the deadbeat predictive control solution and Kalman filter framework, is proposed for unipolar sinusoidal excited switched reluctance motors. The primary aim is to augment the dynamic performance of the system while ensuring robustness across various conditions. To achieve this objective, a Kalman filter is meticulously implemented and integrated into the deadbeat predictive current control strategy (DPCC). This integration facilitates a comprehensive consideration of the system’s nonlinear dynamics and measurement noise, thereby reducing the DPCC’s reliance on precise model parameter information. This advancement significantly bolsters the robustness and flexibility of the control system in various operational contexts. Simultaneously, to enhance the dynamic performance of the speed control mechanism and robustness, a deadbeat predictive speed control strategy (DPSC) integrating a novel adaptive fading Kalman filter (AFKF) is proposed. Within the AFKF, a modified fading factor selection method is employed, which contributes to the enhanced convergence speed, thereby optimizing the dynamic performance of the DPSC strategy. Finally, detailed comparative simulations and experiments are undertaken to verify the theoretical framework’s feasibility and to substantiate the performance enhancements ascribed to the proposed control strategy.

基于自适应衰减卡尔曼滤波器的单极性正弦激励自整定制冷机组的级联死区预测控制
本文针对单极正弦激励开关磁阻电机提出了一种新型级联预测控制策略,该策略具有死区预测控制解决方案和卡尔曼滤波器框架的优点。其主要目的是增强系统的动态性能,同时确保在各种条件下的鲁棒性。为了实现这一目标,卡尔曼滤波器被精心实施并集成到了死区预测电流控制策略(DPCC)中。这种集成有助于全面考虑系统的非线性动态和测量噪声,从而减少 DPCC 对精确模型参数信息的依赖。这一进步极大地增强了控制系统在各种运行环境下的稳健性和灵活性。同时,为了提高速度控制机制的动态性能和鲁棒性,还提出了一种集成了新型自适应衰减卡尔曼滤波器(AFKF)的死区预测速度控制策略(DPSC)。在 AFKF 中,采用了改进的衰减因子选择方法,这有助于提高收敛速度,从而优化 DPSC 策略的动态性能。最后,还进行了详细的对比模拟和实验,以验证理论框架的可行性,并证实所提控制策略的性能提升效果。
