| 3 | 改进永磁同步电机转矩控制精度的措施显示文摘各种各样的实际因素会导致永磁同步电机在求取转矩时很难绝对精确。比如转子温升会导致磁场强度降低并使得输出转矩减小。导致转矩减小的另一种情况是在过载时铁心出现饱和。针对这样的情况,现在比较行之有效的设计思路是使用一个快速叠加速度控制环或者使用转矩传感器。但是,像绞车和注塑成型机一类的设备需要很高的转矩精度,而使用转矩传感器有诸多缺陷。本文将介绍三种不同的改进静态转矩精度的策略。第一种策略是基于对转矩常数和磁阻转矩常数的离线辨识。这一思想在第二种策略中得以扩展,即通过转矩与转距电流之间的关系来识别电机特性。这种策略通过采用多项式方程进行计算来补偿原开环控制的不足。第三种策略是一种在线自适应转矩常数控制技术,它基于对电机电参数的观测和对转速的测量。试验结果证实了三种策略理论的有效性。 | 薛靖 Dr.Guido Stoeppler Dr.Franz Bauer Siemens AG A&D MC Erlangen Germany | 2008 | 电力电子2008,6,1: | 2 |

| 9 | PARTICLE PROPERTIES——PROMISE AND NEGLECT显示文摘We see two major trends in Particle Technology. First, the focus is shifted from unit operations towards functional products, i.e. towards product engineering. Second, modeling will become more and more important. Processes cannot yet be designed from basic molecular understanding. Nanotechnology, however, begins to bridge this gap between molecules and particles and may thus open new ways not only for the production and handling of particulate matter but also for the engineered design of advanced material properties. Starting from the concept of product engineering we investigate the basic preconditions for tailoring nanoparticulate properties, i.e. the control of the particle interactions. Nanotechnology can only be transferred to industrial production if the interactions are effectively controlled.Material and particle properties are essential for predictive models. Although strong tools like MD, DEM or population balance models are available, these models are only predictive if realistic material and particle properties are available which is often not the case. We show for selected examples how particle properties can be obtained by studying the physically relevant elementary processes. The impact breakage behavior of many different materials is described by a master curve. Particle adhesion can be modeled if the roughness of particle and substrate and the Hamaker constant are known. The latter is obtained from adsorption studies. | Wolfgang PeukertInstitute of Particle Technology, Friedrich-Alexander-University Erlangen-Nuremberg, Cauerstr. 4 , 91058 Erlangen, GermanyE-mail: W.
