    摘要： A welding control apparatus according to the present invention includes an integrator for starting calculation of a voltage error integral value Sv2, expressed by a formula (1) given below, from a time when a first pulse period ends and a second pulse period starts in a pulse cycle, based on various data of information regarding a gradient Ks of an external characteristic of a welding power supply and a welding current setting value Is2 and a welding voltage setting value Vs2 both in a second pulse period, which are preset as parameters in the formula (1), as well as on an instantaneous value Io2 of a welding current and an instantaneous value Vo2 of a welding voltage both detected in the second pulse period, a comparator for comparatively determining whether a value of the voltage error integral value Sv2 provided as the calculation result has become 0, and a waveform generator for, per pulse cycle, terminating the relevant pulse cycle and starting a next pulse cycle at a time when the value of the voltage error integral value Sv2 has become 0, whereby a variation in an arc length caused by disturbances is precisely suppressed in pulse arc welding of consumed electrode type: Sv2=∫{Ks(Io2−Is2)+Vs2−Vo2}dt  (1)

    摘要： In a drive system of an AC motor in which a motor current is feedback-controlled, a motor current command is produced in a normal operation according to a torque command value on an optimum efficiency characteristic line so as to select an optimum current phase maximizing an output torque with a constant motor current amplitude. Conversely, when the AC motor produces an excessively generated power exceeding a regeneratable power quantity of the AC motor, a consuming operation is performed for intentionally increasing the power loss in the AC motor. In the consuming operation, the motor current command is produced according to the torque command value on a loss increase characteristic line to change the current phase from the above optimum value. Thereby, the power loss in the AC motor can be increased to consume the surplus power without causing instability in the motor control.

    摘要翻译： 在电动机电流被反馈控制的交流电动机的驱动系统中，根据最佳效率特性线上的转矩指令值，在正常运行中产生电动机电流指令，以选择最佳化电流相位 输出转矩与电动机恒定电流幅度恒定。 相反，当交流电动机产生超过交流电动机的再生电力的过度产生的功率时，进行有意增加交流电动机的功率损耗的消耗操作。 在消耗操作中，根据损耗增加特性线上的转矩指令值产生电动机电流指令，以从上述最佳值改变电流相位。 因此，可以增加AC电动机的功率损耗以消耗剩余功率，而不会导致电动机控制中的不稳定性。
