在许多应用中经常遇到动态变化或难以事先知道的变速转子的主动平衡问题。提出了一种利用多平面主动平衡装置自适应平衡变速转子的新方法。该方法利用了主动平衡系统传递函数的正实性。本文首先证明了主动平衡系统的正实性，并将其与直接自适应控制设计方法相结合。一组仿真结果表明所开发的控制律的有效性。仿真研究表明，新方法达到了预期的效果，对未来的主动平衡控制系统具有潜在的影响。
The problem of active balancing of speed-varying rotors, whose dynamics are changing or hard to be known beforehand, is frequently encountered in many applications. This paper presents a new adaptive method for balancing speed-varying rotors with multi-plane active balancing devices. The new method utilizes the positive realness of the transfer function of the active balancing system. This paper first shows the positive realness of the active balancing system and combines it with a direct adaptive control design method. A set of simulations was conducted to show the validity of the developed control law. The simulation studies show that the new method works as expected and has potential impact on future active balancing control systems.
