摘要:

在资源受限的微控制器上部署神经网络势头强劲,推动了微型神经网络的诸多进展。本文提出了一种微型前馈神经网络TinyFC,将其集成到永磁同步电机(PMSM)的磁场定向控制(FOC)中。比例积分(PI)控制器因其简单性被广泛用于FOC,但其在处理非线性动态方面的局限性阻碍了精度提升。为解决此问题,设计了一个轻量级的1,400参数TinyFC,以增强FOC性能,同时适应微控制器的计算和内存限制。应用了包括剪枝、超参数调优和8位整数量化在内的高级优化技术,以减小模型占用空间,同时保持网络有效性。仿真结果表明,所提方法将超调量显著降低高达87.5%,其中剪枝模型实现了超调量的完全消除,突显了微型神经网络在实时电机控制应用中的潜力。

英文摘要:

The deployment of neural networks on resource-constrained micro-controllers has gained momentum, driving many advancements in Tiny Neural Networks. This paper introduces a tiny feed-forward neural network, TinyFC, integrated into the Field-Oriented Control (FOC) of Permanent Magnet Synchronous Motors (PMSMs). Proportional-Integral (PI) controllers are widely used in FOC for their simplicity, although their limitations in handling nonlinear dynamics hinder precision. To address this issue, a lightweight 1,400 parameters TinyFC was devised to enhance the FOC performance while fitting into the computational and memory constraints of a micro-controller. Advanced optimization techniques, including pruning, hyperparameter tuning, and quantization to 8-bit integers, were applied to reduce the model's footprint while preserving the network effectiveness. Simulation results show the proposed approach significantly reduced overshoot by up to 87.5%, with the pruned model achieving complete overshoot elimination, highlighting the potential of tiny neural networks in real-time motor control applications.
