The Thermal Protector with Single-chip Microcomputer Based on Fuzzy Control

  • 摘要: 针对电动机运行过程中因为绕组温度过高而影响绝缘性能的问题,设计了一种新型的基于模糊控制的单片机热保护器。通过分析和讨论各种标准和热过载模型,提出了最佳的可供单片机热保护器使用的热特性模型,即双时间常数的指数发热和冷却模型及其建模机理。针对电动机热保护器的延迟动作时间选取不准确的问题,利用模糊控制理论设计了热保护器的软件,提高了电动机热保护器的动作精度和可靠性。
    Abstract: Aiming at the problem that excess temperature of windings affects insulating property in running of motor,the paper designed a new thermal protector with single-chip microcomputer based on fuzzy control.Through analyzing and discussing different standards and models of thermal over-loading,the paper put forward an optimal model of thermal characteristic for thermal protector with single-chip(microcomputer),namely exponential model of heating and cooling and its modeling mechanism.For the(inaccurate) problem of the selected delay time of the thermal protector,the paper also designed a set of(software) of the thermal protector with the theory of fuzzy control,which improved the action precision and(reliability) of the thermal protector.
