The following publication describes the method used to calculate current waveforms optimized for minimum RMS value of the current and at the same time ripple-free output torque of the transverse flux reluctance machine. Due to the similarities with switched reluctance machines it is also applicable for this type of electric motors. The method described here, requires detailed characteristics of the...
Wind turbines represent elastically coupled multi-mass systems. Dynamic load changes caused by a gust of wind lead to peaks in the shaft torsion torque and result into high stress for the system. This paper presents an opportunity to integrate a stress minimizing control strategy, which was presented in [7], on wind turbines with doubly fed induction generator (DFIG). To avoid extensive measurements...
Elastically coupled multi-mass systems are a part of many industrial applications, like wind energy plants or drive trains in general. Dynamic load changes often cause peaks in the shaft torsion torque and jerk, resulting in damages to the system. A control strategy to reduce and / or limit this stress was presented in [9], but needed difficult to implement and expensive measurements of the shaft...
Elastically coupled multi-mass systems are found in many industrial applications, like wind energy plants or in robotics. Dynamic load changes often cause peaks in the shaft torsion torque and result in damages to the system. This paper presents a control strategy to reduce the dynamic loads on the drive train and the stress in wind turbines and other multi-mass systems, by directly controlling and...
Controlling a multi-mass system is a common problem in industrial automation. Varying or even unknown parameters cause the difficulty of the control. A powerful tool in order to control systems with uncertain parameters is a robust Hinfin-control. Unfortunately the complex structure and the mathematical theory prevent known Hinfin controllers from the usage in many industrial applications. In this...
Controlling a multi-mass system is a common problem in industrial automation. Varying or even unknown parameters cause the difficulty of the control. A powerful tool in order to control systems with uncertain parameters is a robust H∞-control. Unfortunately the complex structure and the mathematical theory prevent known H∞ controllers from the usage in many industrial applications. In this work the...
