摘 要: 电梯作为高层建筑中重要的运输工具,需要满足快速性和舒适性的基本要求。本文以无齿轮永磁同步电梯曳引机为研究对象,在直接转矩控制原理的基础上,结合空间矢量脉宽调制(space vector pulse width modulation,SVPWM)技术,提出一种基于SVPWM的无齿轮永磁同步曳引机直接转矩控制策略。然后,利用模糊控制算法对传统的比例积分微分(proportion integration differentiation,PID)速度控制器进行优化,将设计的模糊自适应PID速度控制器应用到电梯曳引机调速系统中,并与传统PID控制下的调速系统进行比较。最后,结合抛物线形电梯速度曲线对电梯曳引机调速系统进行分析。仿真结果显示,采用模糊自适应PID控制的电梯曳引机调速系统具有较快的动态响应速度和较强的抗干扰能力,对抛物线形电梯速度曲线具有较好的跟踪性,验证了模糊自适应PID控制算法应用于电梯调速系统的可行性。

Abstract: As an important means of transportation in high-rise buildings, elevators need to meet the basic requirements of speed and comfort. In this paper, the gearless permanent magnet synchronous traction machine for elevator is taken as the research object. Based on the principle of direct torque control and the space vector pulse width modulation (SVPWM) technology, a direct torque control strategy based on SVPWM for gearless permanent magnet synchronous traction machine is proposed. Then, the fuzzy control algorithm is used to optimize the traditional proportion integration differentiation (PID) speed controller, and the designed fuzzy adaptive PID speed controller is applied to the elevator traction machine speed control system and compared with the speed control system under the traditional PID control. Finally, combined with the parabolic elevator speed curve, the elevator traction machine speed control system is analyzed. The simulation results show that the elevator traction machine speed control system with fuzzy adaptive PID control has faster dynamic response speed and stronger anti-interference ability, and has better tracking performance for the parabolic elevator speed curve, which verifies the feasibility of the fuzzy adaptive PID control algorithm applied to the elevator speed control system.
