为保证矿井提升机平稳起降,设计了一种基于模糊算法控制的环流变换器,目标是保证变换器电压输出波形为对称的正弦波.在具体的系统实现中,变换器主回路选择环流控制方式,采用高性能DSP作为模糊控制核心,通过加权平均判决的模糊决策算法对变换器主回路晶闸管的触发角进行调制,从而有效控制输出电压波形.实验结果显示,采用这种模糊控制的环流变换器的电压输出性能得到大幅改善,波形对称且非常接近正弦形,能够保证矿井提升机停位准确,减少冲击. In order to ensure the smooth operation of the mine hoist, a loop-based converter based on fuzzy algorithm is designed to ensure that the voltage output waveform of the converter is a symmetrical sine wave. In the concrete system implementation, Mode, the high-performance DSP is used as the core of fuzzy control, the firing angle of thyristor of the main loop of the converter is modulated by fuzzy decision algorithm of weighted average decision, so as to effectively control the output voltage waveform.The experimental results show that with this fuzzy control loop- Voltage output performance of the device has been greatly improved, the waveform symmetrical and very close to the sine-shaped, to ensure the mine hoist stop accurate and reduce the impact.
