    • The present invention relates to a method of servocontrolling an electric motor during its start-up, comprising at least one step of measuring the speed after a determined duration counting from the commencement of start-up. During a first start-up, the servocontrol system determines the deviation between the value of the measured speed and a preset value. During a second start-up, the servocontrol system modifies at least one duration parameter of the commands applied to the motor as a function of the deviation determined during the first start-up, so as to reduce this deviation in the course of this second step. Advantageously, the start-up comprises three phases making it possible to start the motor while avoiding making it too noisy.
      The invention also relates to an apparatus implementing the method.
    • 本发明涉及一种控制动力到其启动期间电动机的方法,包括从启动时开始确定性开采持续时间计数之后,测量的速度中的至少一个步骤。 在第一启动时,所述伺服控制系统的确定性地雷所测量的速度的值和预设值之间的偏差。 在第二起动时,该伺服控制系统修改施加到发动机作为第一启动期间开采的偏差确定性的函数的命令中的至少一个持续时间参数,以便减少在该第二步骤的过程中这个偏差 , 有利的是,启动包括三个阶段从而可以同时避免使其过于嘈杂启动发动机。 因此,本发明涉及装置上实施该方法。

    • An improved current limiter for electrical circuits utilizes a current limiter, a clock, a memory and a processor. The memory contains a two dimensional table having time data in the first dimension and current data in the second dimension. When a control line is activated, the processor receives timing data from the clock in discrete timing events. For each timing event, the processor looks up a current value using the two dimensional table. The current value is then applied by the processor to a current limiter that limits the current to a circuit. The look up sequence can utilize discrete (rounded) timing values, linear interpolation, curve fit interpolation, or other interpolation techniques that can be processed by the processor. The two dimensional table can be pre-loaded from an external source or, in the alternative, the processor can calculate the discrete time values and current values and then load the two dimensional table before operation of the device.
    • 用于电路的改进的限流器利用限流器,时钟,存储器和处理器。 存储器包含在第一维和电流数据在第二维度的二维表具有时间数据。 当控制线被激活时,处理器接收来自于离散的定时事件的时钟定时的数据。 对于每个定时事件,所述处理器查找使用二维表的电流值。 的电流值,然后由处理器应用到一个电流限制器限制那样的电流的电路。 所述查找序列可以利用离散的(四舍五入)定时值,线性内插,曲线拟合内插,或其他插值技术也可以由处理器进行处理。 二维表可以从外部源预先加载到或在替代方案中,处理器可以计算出离散时间值和当前值,然后该装置的手术前加载二维表。
