【摘要】：隨著我國經(jīng)濟的增長，電梯行業(yè)一直保持注旺盛的需求，特別在大中型城市，，由于電梯作為快捷的代步工具在人們?nèi)粘５纳钪衅鹬絹碓街匾淖饔�。而電梯門機又屬于整個電梯系統(tǒng)中需要頻繁動作的部分，其運行是否可靠直接影響到整個電梯系統(tǒng)的品質(zhì)，所以保障電梯門機的正常工作在整個電梯系統(tǒng)中起到非常重要的作用。 本文對電梯門機驅(qū)動器進行了功能需求分析，其中包括傳統(tǒng)速度曲線設(shè)計方法和本文提出的改進速度曲線設(shè)計方法，電機偏移角自學習方法，門寬自學習方法，交互功能設(shè)計。在控制算法方面，介紹了永磁同步電機基于轉(zhuǎn)子磁場定向的矢量控制算法。并比較了不同調(diào)節(jié)器對控制效果的影響，包括傳統(tǒng)PI調(diào)節(jié)器和改進的模糊自適應PI調(diào)節(jié)器。之后分別介紹了驅(qū)動器的硬件模塊與軟件框架，其中硬件模塊包括電源模塊，逆變模塊，交互模塊，故障檢測模塊，采樣檢測模塊和主控模塊；軟件架構(gòu)包括整體軟件架構(gòu)，門機運行控制策略，門機矢量控制流程。最后在實際平臺上測試驅(qū)動器的開關(guān)門運行，能夠平穩(wěn)控制門機運行，達到了設(shè)計要求。
[Abstract]:With the economic growth of our country, elevator industry has been keeping a strong demand, especially in large and medium-sized cities, because the elevator as a quick walking tool plays a more and more important role in people's daily life. And the elevator door crane belongs to the part of the elevator system that needs frequent action. Whether its operation is reliable or not has a direct impact on the quality of the whole elevator system. So ensuring the normal operation of elevator door crane plays a very important role in the whole elevator system. In this paper, the functional requirements of elevator gantry driver are analyzed, including the traditional speed curve design method, the improved speed curve design method proposed in this paper, the motor offset angle self-learning method, the gate width self-learning method, and the interactive function design. In the aspect of control algorithm, the vector control algorithm of permanent magnet synchronous motor (PMSM) based on rotor field orientation is introduced. The effects of different regulators on the control effect are compared, including the traditional PI regulator and the improved fuzzy adaptive PI regulator. Then the hardware module and software framework of the driver are introduced respectively. The hardware module includes power module, inverter module, interactive module, fault detection module, sampling detection module and main control module. The software architecture includes the whole software architecture, the door crane operation control strategy, the door crane vector control flow. Finally, the running of the driver is tested on the actual platform, which can control the running of the door crane smoothly and meet the design requirements.
