为了提高直接转矩控制(DTC)系统定子磁链估计精度,降低电流、电压测量的随机误差,提出了一种基于扩展卡尔曼滤波(EKF)实现异步电机转子位置和速度估计的方法。扩展卡尔曼滤波器是建立在基于旋转坐标系下由...
微电脑型单相交流集合式电表(单相二线系统) 特点: 精确度0.25%满刻度±1位数 可同时量测与显示交流电压,電流,頻率,瓦特,(功率因數/視在功率) 交流電壓,電流,瓦特皆為真正有效值...
集合式直流电能表(小功率的) 特点: 精确度0.05%满刻度±1位数 可同时量测与显示/直流电压/电流/瓦特(千瓦)/瓦特小时(千瓦小时) 电压输入(DC0-99.99V/0-600.0...
因为测量系统都用50欧姆, 如非特指, 以下所说的Gain均指功率增益(Power Gain). 但是一般的接收机的输入输出并非50欧姆, 因此有必要考虑电压增益(Voltage Gain)....
