在容错控制(FTC)系统中，控制的动态重构的概念是众所周知的。重点介绍了这一概念的基本思想，并对其进行了扩展，以实现工厂在其整个运行区域内的最佳性能。今天，许多工业标准驱动器为驱动器控制提供了不止一种控制方案。客户可以在例如磁通定向控制(FOC)和恒压频率比控制(V/F)之间进行选择。然而，这些控制方案之间的动态(运行中)转换通常不能作为一种功能，尽管它可能是必不可少的，例如在以最佳方式处理不同运行模式的情况下，或者作为故障情况下的后备策略。本文重点介绍了感应电机控制方案动态重构的具体概念、实现方法和实验验证。其思想不仅是展示不同控制方案之间的切换，而且还利用现场可编程门阵列(现场可编程门阵列)作为控制器实现的基础。FPGA固有的并行执行特性使得在单一控制平台上实现这种动态可重构的控制结构变得容易。
Abstract The concept of dynamic reconfiguration of controls is commonly known in Fault Tolerant Control (FTC) systems. The general idea of this concept is highlighted and that can be extended to achieve the optimal performance from a plant in its whole operating region. Today, many industrial standard drives provide more than one control scheme for the drive control. The customer may chose between, e.g., flux-oriented control (FOC) and constant voltage frequency ratio control (v/f). However, the dynamic (on-the fly) change-over between these control schemes is usually not available as a feature, although it may be essential e.g. in cases of handling different operating modes optimally or as a fallback strategy in case of faults. The main emphasis of this contribution is to present the detailed concept, implementation and the experimental validation of dynamic reconfiguration between the well known control schemes for the induction machine. The idea is not only to show the switch-over between different control schemes, but also to utilize field-programmable gate arrays (FPGA) as basis for controller implementation. The inherent parallel execution of FPGA makes it easy to implement such dynamically reconfigurable control structure on a single control platform.
