摘要

本文介绍了在无外部干扰情况下,非平滑气隙永磁同步电机(NSAG-PMSM)的分析和控制方法。对 NSAG-PMSM 的分析研究表明存在平衡点。基于 Routh-Hurwitz 准则,平衡点的稳定性揭示了跨临界分岔的存在。NSAG-PMSM 表现出多种动力学行为,如双稳态混沌、周期性尖峰振荡、混沌尖峰特性、周期性和混沌行为共存,以及随着系统参数变化向单稳态混沌的周期性演变。该研究使用微控制器来验证在 NSAG-PMSM 数值模拟中观察到的动态特性。对 NSAG-PMSM 的研究提出了使用两个简单控制器缓解混乱和稳定系统的策略,并使用峰值过冲和稳定时间图进行了比较研究。通过将这些不同方面结合起来,本文极大地促进了对 NSAG-PMSM 运行的理解,突出了与微控制器技术在电气工程领域的应用和混沌控制解决方案相关的具体方面。

Analysis, microcontroller implementation and chaos control of non-smooth air-gap permanent magnet synchronous motor

This article presents an analysis and control approach for a non-smooth air-gap permanent magnet synchronous motor (NSAG-PMSM) in the absence of external disturbances. The analytical study of NSAG-PMSM shows the existence of equilibrium points. Based on the Routh–Hurwitz criterion, the stability of the equilibrium points reveals the existence of transcritical bifurcation. NSAG-PMSM exhibits various dynamical behaviours, such as bistable chaos, periodic spiking oscillations, chaotic spiking characteristics, coexistence between periodic and chaotic behaviours and periodic evolution towards monostable chaos as system parameters change. The research uses microcontroller implementation to validate the dynamical characteristics observed during the numerical simulations of the NSAG-PMSM. The study of NSAG-PMSM proposes a strategy to mitigate chaos and stabilise the system using two simple controllers, with a comparative study presented using peak overshoot and settling time diagrams. By combining these different aspects, this article significantly contributes to the understanding of the operation in NSAG-PMSM, highlighting specific aspects related to the application of microcontroller techniques in the field of electrical engineering and solutions to chaos control.
