【摘要】：隨著城市化進(jìn)程的推進(jìn),電梯已經(jīng)成為人們生活中必備的運(yùn)載工具。中國是全球最大的電梯生產(chǎn)國和消費(fèi)國,但本土電梯品牌長期在曳引機(jī)驅(qū)動(dòng)控制技術(shù)上受制于人,發(fā)展我國自主的電梯高性能驅(qū)動(dòng)控制技術(shù)是縮短國內(nèi)外差距、開拓市場(chǎng)份額的必經(jīng)之路。本文針對(duì)曳引機(jī)控制中存在的技術(shù)難點(diǎn),研究了永磁同步曳引機(jī)驅(qū)動(dòng)與控制中若干關(guān)鍵技術(shù),主要工作與成果如下:(1)對(duì)采用傳統(tǒng)串級(jí)PI控制的曳引機(jī)矢量控制系統(tǒng)進(jìn)行了研究,結(jié)合曳引機(jī)控制的具體需求,針對(duì)PI控制器存在的不足,在電流環(huán)和速度環(huán)中分別引入解耦補(bǔ)償控制和多模態(tài)切換控制,并進(jìn)行了仿真驗(yàn)證。(2)分析了曳引機(jī)啟動(dòng)時(shí)的轉(zhuǎn)子初始位置檢測(cè)問題,提出了一種利用正弦波增量式編碼器換向信號(hào)計(jì)算轉(zhuǎn)子初始位置的方法,滿足了曳引機(jī)拖動(dòng)的實(shí)際應(yīng)用需求。(3)分析了因編碼器量化誤差導(dǎo)致的低速抖動(dòng)問題以及負(fù)載擾動(dòng)對(duì)曳引機(jī)運(yùn)行性能的影響,基于卡爾曼濾波的原理,分別了設(shè)計(jì)轉(zhuǎn)速、轉(zhuǎn)矩觀測(cè)器,改善了曳引機(jī)低速運(yùn)行性能,實(shí)現(xiàn)了曳引機(jī)抗擾動(dòng)控制,有效提高了電梯曳引機(jī)系統(tǒng)全速度段的調(diào)速性能指標(biāo)。(4)基于自行研制的曳引機(jī)驅(qū)動(dòng)控制系統(tǒng),完成了曳引機(jī)驅(qū)動(dòng)控制軟件的研發(fā),包括電機(jī)運(yùn)行狀態(tài)檢測(cè)模塊、轉(zhuǎn)速、轉(zhuǎn)矩觀測(cè)器模塊、轉(zhuǎn)速、電流調(diào)節(jié)器模塊和PWM信號(hào)發(fā)生模塊。以上方法在實(shí)際系統(tǒng)中進(jìn)行了測(cè)試,結(jié)果表明:本文提出的永磁同步曳引機(jī)驅(qū)動(dòng)控制算法是有效的,對(duì)給定的電梯運(yùn)行速度曲線具備良好的跟蹤性能。
[Abstract]:With the city development, the elevator has become the vehicle for people's life. China elevator is the world's largest producer and consumer, but the domestic elevator brand long-term in the machine drive control technology on the development of China's own heteronomy, the high performance of the elevator drive control technology is to shorten the gap between domestic and foreign market development the only way which must be passed. Share. Aiming at the technical difficulties of traction machine control, the permanent magnet synchronous traction machine drive and some key technologies of control, the main work and results are as follows: (1) on the traction machine vector control system of traditional cascade PI control are studied, combined with the specific needs of the traction machine control. Lack of the presence of the PI controller, the current loop and speed loop are introduced decoupling compensation control and multi-mode switching control, and simulation experiment is carried out. (2) analysis of the traction machine 鍚姩鏃剁殑杞瓙鍒濆浣嶇疆媯，
