• Flux observer for induction machine control. Part I - Sensitivity analysis as a function of sampling rate and parameters variations
  作者：E. Delmotte、B. Semail、B. Robyns、J. P. Hautier

  DOI：10.1051/epjap:2001136

  日期：2001.4

  In the last decades, many vector control techniques have been developed for induction machine to increase their dynamic performances. But they are based on an accurate estimation of flux variables, which are not measurable in conventional induction machines. So, observer strategies are used in induction machine controls. Complex algorithms have been developed, but their long calculation time does not allow a simple implementation in digital form. For this reason, reduced-order observers are often used when a real-time estimation is implemented. If these structures lead to better flux estimations than in the case of an open-loop model, their convergence gains have to be determined and they are sensitive to the parameters value. The authors present a new analytical method to elaborate a reduced-order observer. The influence of the sampling rate is taken into account and the paper investigates the optimal gain, which minimise the sensitivity to the parameters value. In order to measure the observer robustness, the authors define two criteria, which are computed in steady state: the orientation error and the modulus error of the rotor flux. Some examples illustrate the theory and their calculation results are presented.

  在过去几十年中，为了提高感应电机的动态性能，开发了许多矢量控制技术。但这些技术依赖于对流量变量的准确估计，而在传统感应电机中，这些变量是不可测量的。因此，控制感应电机时采用了观察者策略。虽然已经开发了复杂的算法，但它们的长计算时间使得在数字形式中简单实现变得不够可行。因此，当实现实时估计时，通常会使用降阶观察者。如果这些结构在估计流量方面比开环模型表现更好，则需要确定它们的收敛增益，并且它们对参数值非常敏感。作者提出了一种新的分析方法来制定降阶观察者。考虑了采样率的影响，论文研究了最优增益，以最小化对参数值的敏感性。为了衡量观察者的鲁棒性，作者定义了两个标准，这些标准在稳态下进行计算：转子流量的方向误差和模值误差。一些例子展示了理论，并呈现了它们的计算结果。
• Theoretical and Experimental Investigation of the Dynamic Behaviour of Centrifugal Fans
  作者：G. Mariaux、Y. Gervais、L. Crespeau

  DOI：10.1155/s1023621x0000021x

  日期：——

  In this paper, a theoretical model is proposed to investigate the centrifugal fans' transient behaviour in response to sudden imposed changes in pressure or flow rate. We are especially interested in the dissipative or creative energy transient behaviour of the fans located in actual aeraulic networks.

  The model is based on the global modelisation of the motor and resistant torques (due to pressure and viscosity actions on the blades) which are present on the rotor and by their coupling with its inertia.

  The model is then validated by experimental measurements which show its validity. In the case of the tested fan, the instantaneous characteristics (in particular the flow rate and rotation speed) have been correctly predicted by the model, with regard to time as well as amplitudes, provided the flow is not reversed.

  本文提出了一个理论模型，用于研究离心风机在压力或流量突然变化时的瞬态行为。该模型基于转子上存在的电机和阻力矩（由于叶片上的压力和粘度作用）的全局建模，以及它们与转子惯性的耦合。在测试的风机中，只要流量不逆转，模型就能正确预测瞬时特性（尤其是流速和转速）的时间和振幅。
