PMSM

设备管理系统，采用vc++及sql2000，odbc(Equipment management system vc++ and sql2000 )

说明：  A、名称：限幅滤波法（又称程序判断滤波法） B、方法： 根据经验判断，确定两次采样允许的最大偏差值（设为A）， 每次检测到新值时判断： 如果本次值与上次值之差A，则本次值无效，放弃本次值，用上次值代替本次值。 C、优点： 能有效克服因偶然因素引起的脉冲干扰。 D、缺点： 无法抑制那种周期性的干扰。 平滑度差。(A. Name: Limited filter method (also known as program judgement filter method) B. Method: Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined. Judge each time a new value is detected: If the difference between the current value and the previous value is
