摘要
本文介绍一种微机振动控制系统，该系统以微机为主控单元，硬件组成简单、紧凑，振动驱动信号的生成与控制主要由系统软件完成。在其随机信号的均衡过程中，该系统采用随机化噪声抵消技术对驱动谱进行实时修正，其均衡速度与经典的多次采样平均方式相比有较大提高。
This paper introduces a microcomputer vibration control system,which uses a microcomputer as its main control unit.The hardware components are brief and compact.The producing and the controlling of the vibration exciting signal are performed mainly by its software.Moreover,suring the equalization process with true-random signal excitation.the system uses randomization noise balancing technique to modify the auto-power spectrum of exciting signal,thus,the time of equalization is much less than that of the traditional equalization method which takes the average value of many sample spectra.
