摘要
地板水暖是一种新型的房间采暖技术,为了提高地板水暖系统的整体性能、改善调速性能、节能降耗、降低成本和节约空间,水泵电机采用无速度传感器永磁同步电机(PMSM)矢量控制系统。在理论分析PMSM滑模观测器矢量控制原理的基础上,设计和实现了地板热水供暖的变频调速传动系统,描述了该系统的设计过程,给出了有关MATLAB/Simulink仿真波形和基于TMS320F2401控制器的实测波形,整个系统效率高达35%。
Low temperature hot-water floor heating system was a new room heating method.In order to improve the performance of hot-water floor heating system and speed regulating,decrease energy consumption,reduce cost and save space,pump motor should use permanent magnet synchronous motor controlled by adopting the technology of sliding mode observer for sensorless vector control.Based on the theoretical analysis of sliding mode observer for sen-sorless vector control,variable frequency drive system of hot-water floor heating system was designed and realized.The design process of the system was given.The simulation waveforms utilizing MATLAB/Simulink and measured waveforms on the basis of TMS320F2401 DSP were shown.The results showed that the efficiency of the whole system can reach 35%.
