摘　　要：针对太阳能、地源热泵供暖系统节能控制时出现的转子磁链观测器的观测值与实际值误差较大的问题,提出一种新型带权重c的混合磁链观测方法。该方法通过Simulink建立基于矢量控制、空间矢量脉宽调制、模糊控制相结合的仿真模型。仿真结果通过与一般的磁链观测器进行对比,表明在不同的调制比下,带权重c的混合磁链观测器更加接近实际磁链值,并且具有参数可调,系统应用灵活等优势,为解决当前由于散煤供暖造成的环境污染问题,提供了一个新思路。Aiming at the large deviation between the observed value and the actual value of rotor flux observer, and according to the energy saving control of solar energy and ground source heat pump heating system, the paper proposed a new hybrid flux observer with weight c. The simulation model is based on vector control, space vector pulse width modulation and fuzzy control. Compared with the general flux observer, under different modulation index, the hybrid flux estimator with weight c is more close to the actual flux value and has the advantages of adjustable parameters and flexible application, which provides a new idea to solve the environmental pollution problem caused by the coal powder heating.
