    • An active system for controlling vibration or sound. The system includes a method for limiting the output gain G from a gradient descent algorithm, such as an LMS algorithm, according to the relationship ##EQU1## and reducing one of first and second filter weights W.sub.1 and W.sub.0 such that G.ltoreq.G.sub.max ensuring the output canceling signal is never saturated. This eliminates the square wave shape which may impart unwanted harmonics or resonances to the dynamic system. In another aspect, the system eliminates drift of the output devices toward saturation when situations are encountered such as singularities in the quadratic performance surface. This is accomplished by applying leakage factor r(k) to a function f(k) at or near a predetermined limit to avoid saturation of the output device. The function f(k) can be the gain G or the weights W(k). Another aspect is to provide a constant, optimum, and stable adaptation rate in an LMS system by providing an optimum adaptation coefficient .mu..sub.opt that provides a constant, uniform, and optimum adaptation rate on a per period basis for all frequencies. Various combinations of the above are described and are useful in active control systems.
    • 用于控制振动或声音的主动系统。 该系统包括根据关系的梯度下降算法(例如LMS算法)来限制输出增益G的方法! 并且减少第一和第二滤波器权重W1和W0中的一个,使得确保输出消除信号的G max绝对不会饱和。 这消除了可能给动态系统带来不需要的谐波或谐振的方波形状。 在另一方面,当遇到诸如二次性能表面中的奇异点的情况时,系统消除输出装置朝向饱和的漂移。 这是通过在等于或接近预定极限的函数f(k)应用泄漏因子r(k)来实现的,以避免输出装置的饱和。 函数f(k)可以是增益G或权重​​W(k)。 另一方面是通过提供在每个周期基础上为所有频率提供恒定,均匀和最佳适应速率的最佳适配系数mu opt,在LMS系统中提供恒定的,最佳的和稳定的适应速率。 描述上述各种组合,并且在主动控制系统中是有用的。
