【摘要】：转塔式测试分选机是一种可以完成对集成电路产品进行打印、图像检测以及电性能测试,并且根据这些检测的结果,将集成电路产品进行分类以及包装成最终商品的自动化设备。随着我国半导体集成电路封装测试产业的飞速发展,大型集成电路封装企业对转塔机的运行要求不断提高,特别是针对下压机构在高速运行时集成电路与测试簧片保持稳定的接触力。本课题就转塔机下压机构力矩控制技术展开了深入研究。本课题分析了永磁同步电机(PMSM)基本结构和在各个坐标系下的数学模型。通过对永磁同步电机几种主流的控制策略进行了介绍以及对比分析,选取了能满足企业需求的直接转矩控制(DTC)策略并对其做了详细的介绍。针对传统DTC系统存在的磁链和转矩脉动过大的缺点,下压机构准备采用了基于空间矢量脉宽调制(SVPWM)的直接转矩控制(SVM-DTC)策略。然后使用Matlab/Simulink工具对控制系统进行仿真分析,仿真结果充分证明了SVM-DTC策略的有效性以及该策略应用到下压机构的可行性。在仿真分析的基础上,采用了高性能数字信号处理器(DSP)TMS320F28335作为控制电路的核心,配合智能功率模块(IPM),完成了转塔机下压机构的控制系统设计,实现了下压电机力矩控制。通过对比传统DTC系统和SVM-DTC系统的电流电压测量结果,证实了SVM-DTC策略控制效果更佳的结论,这与之前的仿真结果一致,为以后转塔机下压机构力矩控制的实现奠定了基础。
[Abstract]:Turret test sorting machine is a complete print of the integrated circuit products, image detection and electrical performance tests, and according to these results, the integrated circuit products classification and automation equipment packaged into final goods. With the rapid development of China's semiconductor IC packaging and testing industry, large scale integrated circuit packaging enterprises to improve the operation requirements of tower crane, especially for the contact force under pressure mechanism in high speed operation of integrated circuit and test spring steady. This topic is to tower crane pressing mechanism torque control technique is deeply studied. This thesis analyzes the permanent magnet synchronous motor (PMSM) and the basic structure in each coordinate system of mathematical models are introduced. And through the analysis and comparison of control strategy of permanent magnet synchronous motor of several mainstream, selected to meet the needs of business Direct torque control (DTC) strategy and made a detailed introduction on it. According to the flux and the torque ripple of traditional DTC system have the disadvantages of large press agency is prepared to use the space vector pulse width modulation (SVPWM) based on the direct torque control (SVM-DTC) strategy. And then use the Matlab/Simulink tool for the simulation of the control system and the simulation results demonstrate the effectiveness of the SVM-DTC strategy and the strategy applied to the feasibility of pressing mechanism. Based on the analysis of simulation, the high performance digital signal processor (DSP) TMS320F28335 as the core of the control circuit with intelligent power module (IPM), completed the design of the control system of tower crane rotary pressure mechanism next, the pressure under the control of the motor torque. The current voltage measurement results compared with the traditional DTC system and SVM-DTC system, confirms SVM-DTC control strategy with better effect, this It is consistent with the previous simulation results, which lays a foundation for the realization of the torque control of the lower pressure mechanism of the later tower.
