摘要： A system and method for detecting structural damage is provided that utilizes a general order perturbation methodology involving multiple perturbation parameters. The perturbation methodology is used iteratively in conjunction with an optimization method to identify the stiffness parameters of structures using natural frequencies and/or mode shape information. The stiffness parameters are then used to determine the location and extent of damage in a structure. A novel stochastic model is developed to model the random impact series produced manually or to generate a random impact series in a random impact device. The random impact series method or the random impact device can be used to excite a structure and generate vibration information used to obtain the stiffness parameters of the structure. The method or the device can also just be used for modal testing purposes. The random impact device is a high energy, random, and high signal-to-noise ratio system.

摘要： Systems and devices for ripple reduction in a DC/DC converter are presented. The disclosed systems and methods enable ripple reduction in discontinuous conduction mode (DCM) operation. In DCM, the inductor current peak to peak ripple may be reduced based on the load current. To achieve the reduction of the inductor peak to peak current ripple, a digital counter is used to count the time between consecutive PWM pulses. The digital output of the counter is used to control the pulse width modulation. As the digital output of the counter increases, the PWM on-time decreases. Since the PWM pulse is demanded by the load in DCM mode, the peak to peak inductor ripple is modulated by the counter, or, in turn, modulated by the load current.
摘要翻译：介绍了DC / DC转换器中纹波降低的系统和器件。所公开的系统和方法使得不连续导通模式（DCM）操作中的纹波降低。在DCM中，电感电流峰峰值纹波可能会根据负载电流而减小。为了实现电感峰值电流纹波的降低，使用数字计数器对连续PWM脉冲之间的时间进行计数。计数器的数字输出用于控制脉宽调制。随着计数器的数字输出增加，PWM导通时间减少。由于PWM模式下的负载要求PWM脉冲，所以峰值电感纹波由计数器调制，或由负载电流调制。
