【摘要】：随着我国经济的增长，电梯行业一直保持注旺盛的需求，特别在大中型城市，，由于电梯作为快捷的代步工具在人们日常的生活中起着越来越重要的作用。而电梯门机又属于整个电梯系统中需要频繁动作的部分，其运行是否可靠直接影响到整个电梯系统的品质，所以保障电梯门机的正常工作在整个电梯系统中起到非常重要的作用。 本文对电梯门机驱动器进行了功能需求分析，其中包括传统速度曲线设计方法和本文提出的改进速度曲线设计方法，电机偏移角自学习方法，门宽自学习方法，交互功能设计。在控制算法方面，介绍了永磁同步电机基于转子磁场定向的矢量控制算法。并比较了不同调节器对控制效果的影响，包括传统PI调节器和改进的模糊自适应PI调节器。之后分别介绍了驱动器的硬件模块与软件框架，其中硬件模块包括电源模块，逆变模块，交互模块，故障检测模块，采样检测模块和主控模块；软件架构包括整体软件架构，门机运行控制策略，门机矢量控制流程。最后在实际平台上测试驱动器的开关门运行，能够平稳控制门机运行，达到了设计要求。
[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.
