摘　　要：目的研究一种借助多目标优化模型求得电梯理想速度曲线的确定方法,解决乘客电梯快速性和舒适性问题.方法分析电梯实际运行方式,构建理想速度曲线组合模式;结合实际及相关国家标准,建立求取理想速度曲线参数的多目标优化模型;借助多目标遗传算法NSGA-Ⅱ解得理想速度曲线参数的Pareto解集,并基于偏好进行区域划分.结果通过对电梯速度曲线参数的多目标优化求解,获得不同偏好的乘客电梯理想速度曲线.结论不同偏好、不同额定速度下电梯理想速度曲线对比分析结果表明,基于多目标优化的乘客电梯理想速度曲线确定方法在兼顾电梯运行的快速性及舒适性要求的同时为技术人员提供了多种可供选择的运行速度控制模式;对额定速度不高于3.5 m/s的乘客电梯,其理想速度曲线可省去直线加速段以降低速度控制模式的复杂性.This paper studies a method of determining elevator ideal velocity curve by means of multi- objective optimization model to solve the problems of rapidity and comfort of passenger elevator. The paper analyzes practical operation mode of elevator and construct the combination pattern of ideal velocity curve. Combined with the actual and related national standards, the multi-objective optimization model of getting ideal velocity curve parameters is established. With the help of multi-objective genetic algorithm NSGA- 11, the Pareto solution set of ideal velocity curve parameters can be obtained to carry out regional division based on preference. Through solving the parameters of elevator velocity curve by multi-object optimization, the ideal velocity curves with different preferences of passenger elevator can be acquired. The comparison and analysis results of elevator ideal velocity curve under the conditions of different preferences and different rated velocities show that, the method of determining elevator ideal velocity curve by means of multi-objec- tive optimization provides a variety of alternative control modes of running speed for technical staff while en- suring the elevator requirements of working rapidity and comfort. For the passenger elevators with rated speed no more than 3.5m/s, the acceleration section of ideal velocity curves can be omitted to reduce the complexity of speed control mode.
