Description: 无刷直流电机无位置传感器控制技术的研究(博士论文)无刷直流电动机利用电子换相代替机械换相，不但具有直流电动机的调速性能，而且体积小、效率高，在许多领域已得到了广泛应用。采用无位置传感器控制技术之后，不但克服了外置式位置传感器的诸多弊病，而且进一步拓宽了无刷直流电机的应用领域。目前，无刷直流电机无位置传感器控制已成为无刷直流电机控制技术的发展方向。 本文纵观了无刷直流电动机的兴起、发展与现状，概括了无刷直流电动机无位置传感器控制技术的现有水平及存在的问题，以研制、开发全直流变转速空调产品为依托，从理论和实践两个方面对这些问题展开了较为全面的研究和讨论。 (1)针对反电动势过零点检测方法和换相点检测方法中存在的不足，分别提出了“延迟90°-α换相”和“超前60°-γ换相”的方法。同时，本文提出的软件、硬件相结合的换相原理突破了单纯依靠硬件电路换相的局限性，拓宽了系统的调速范围，提高了系统的稳定性和可靠性。 (2)本文详细阐述了无刷直流电机控制系统中的换相转矩脉动问题，分析了造成换相转矩脉动的原因，通过理论推导，创造性地给出抑制换相转矩脉动的方法，并利用计算机仿真手段及实验对这种换相转矩脉动抑制方法进行了验证。-R&D on Sensorless Control Technology for Brushless DC Motor Brushless DC motor with permanent magnet excitation, in which electrical commutator is used instead of mechanical, has the same good characteristics of speed control as traditional DC motor. Brushless DC motors have found wide application due to their high power density and ease of control. Moreover, the machines have high efficiency over wide speed range.
