【摘要】 随着社会的发展,电梯已成为当今世界高层建筑中不可缺少的交通运输工具。电梯门机系统是电梯系统的重要组成部分,驱动与控制一体化的门机控制系统将提高开关门性能,使电梯整体性能得到显著改善。受日立电梯(中国)有限公司广州大石工厂的委托,本项目研制出集电梯门电机驱动控制与电梯门逻辑控制于一体的控制系统,该系统已由广州大石工厂生产和小规模试用。本论文给出了采用恒压频比(VVVF)与空间矢量脉宽调制(SVPWM)方法驱动控制门机系统中三相异步电动机的驱动控制方案,并在MATLAB/Simulink平台上进行了计算机仿真。仿真结果表明,本方案实现了电梯门机的平稳、快速控制,并具有电流谐波分量小的优点,符合电梯门机系统的使用要求。本论文设计出了电梯门机控制系统硬件,包括控制单元、功率变换单元,并进行了电磁兼容性设计。控制单元以TI的TMS320LF2407A DSP控制器为核心,设计了编码器接口电路、人机界面电路、参数存储电路、门机输入输出接口电路、通信电路等;功率变换单元以三菱的IPM PS21563-P为核心,设计了能耗制动电路、信号采样与调理电路,以及多项保护电路,其中信号采样与调理电路包括电机相电流采样电路、直流母线电压采样电路及二阶有源低通滤波器电路。本论文基于TMS320LF2407A DSP控制器设计出了电梯门机控制系统的电机驱动控制程序和电梯门机控制任务程序,其中电梯门机控制任务程序包括电梯门逻辑控制程序、门机运行曲线计算程序、人机界面程序、门宽自适应程序以及各项安全保护程序等。本论文研究了电梯门机的门重及风压变化对电梯门开、关性能的影响,提出了门重自适应控制及风压自适应控制方法,并通过基于MATLAB/Simulink平台的计算机仿真实验,验证了该方法的正确性和有效性。本论文研制的电梯门机控制系统,在日立电梯(中国)有限公司广州大石工厂的实验中心进行了试验,试验内容包括电磁兼容试验、开关门时间测试、噪音测试等,试验结果符合国家标准及日立企业标准。

【Abstract】 With the development of society,the elevators have become indispensable transportation vehicle in the high-rise building in today’s world.Elevator door system is an important component of the elevator system,and the elevator door control system integrated with drive and control will enhance the door opening and closing performance,and improve the whole performance of the elevator remarkably.Entrusted by Hitachi Elevator(China)Co.,Ltd. Guangzhou Dashi Factory,this project has developed a control system integrated with the elevator door motor drive control and the elevator door logic control,this system has been produced by Guangzhou Dashi Factory and used in small scale.This thesis presents a drive and control scheme about using VVVF and SVPWM to drive the 3-phase ACI motor of the elevator door system,and this drive and control scheme is simulated based on MATLAB/Simulink.The simulation result indicates that,this scheme achieves smooth and rapid control to the elevator door,and has the characteristic of low current harmonic,achieving the application requirement of the elevator door system.This thesis designs the hardware of the elevator door control system,including the control unit and the power conversion unit,and designs the hardware’s EMC.The control unit uses the TI’s DSP TMS320LF2407A as the core,designs the encoder interface circuit,human-machine interface circuit,parameters storage circuit,elevator door I/O interface circuit,communication circuit etc.Power conversion unit uses the MITSUBISHI IPM PS21563-P as the core,designs the energy-consumption brake circuit,signal sampling and conditioning circuits,and several protection circuits,and the signal sampling and conditioning circuits include the motor phase currents sampling circuits,DC-Bus voltage sampling circuits and the 2nd-order active low-pass filter circuit.This thesis designs the motor drive and control program and elevator door control task program of the elevator door control system based on DSP TMS320LF2407A,and the elevator door control task program includes the elevator door logic control program,elevator door running curve calculation program,human-machine interface program,door-width adaptive program and the system protection program etc. This thesis studies the influence of elevator door weight and air pressure on the opening and closing performance of the elevator door,then presents the elevator door weight adaptiv control method and air pressure adaptive control method,and the computer simulations based on MATLAB/Simulink validate the validity and effectiveness of these adaptive control methods.The elevator door control system developed in this thesis is tested in the Hitachi Elevator(China)Co.,Ltd Guangzhou Dashi Factory experiment center,the test contents include EMC test,door opening and closing time test,noise test etc,the test result conforms to the national standard and Hitachi enterprise standard.
