    • PROBLEM TO BE SOLVED: To solve the problem wherein, when storing point sequence data showing a temporal change of a position, velocity or acceleration into a memory of a self-propelled vehicle as it is, the data oppresses the memory to press for large capacity. SOLUTION: When mounting a pattern ((c) in Fig. 2) drawn by the point sequence data showing the temporal change of the acceleration imparted to a motor of a stacker crane 1 as an instruction value to an actual machine of the stacker crane 1, a curve function that is an approximation expression of the point sequence data is derived in a form of Fourier series having a finite number of terms, with time as an independent variable, with the acceleration as a dependent variable, and data specifying the Fourier series having the finite term number are stored in the memory 5 mounted in the stacker crane 1.

    • PROBLEM TO BE SOLVED: To prevent the time required for a carriage to reach the target stop position from getting longer.
      SOLUTION: In case that the travel speed Vn of a carriage computed by a velocity converter is larger than the assumed velocity Va in the deceleration zone of the carriage (s420:YES), this motor controller can perform the braking by the braking method (s450, s460) geared to the controlled output Uo generated by a motor control unit. By performing such braking, the travel speed of the carriage gets to drop to the assumed velocity Va by braking. At this time, the braking to the carriage is performed, according to the deviation between the target velocity Vt and the travel velocity Vn and the deviation between the present position Xn and the target stop position Xt, so even if the braking force required to perform the braking to the carriage varies with individual difference of a carriage controller or conditions such as the operation state of the carriage, etc., it can brake the carriage by the braking force geared to the conditions.

    • 要解决的问题:为了防止运输到达目标停止位置所需的时间越来越长。 解决方案:如果由速度转换器计算的滑架的行驶速度Vn大于滑架减速区域中的假定速度Va(s420:是),则该电机控制器可以通过制动执行制动 方法(s450,s460)适用于由电机控制单元产生的受控输出Uo。 通过进行这种制动,滑架的行进速度通过制动下降到假设速度Va。 此时,根据目标速度Vt和行进速度Vn之间的偏差以及当前位置Xn与目标停止位置Xt之间的偏差来执行对滑架的制动,因此即使执行所需的制动力 对滑架的制动根据滑架控制器的个体差异或诸如滑架等的操作状态的状况而变化,它可以通过适应于该条件的制动力来制动滑架。 版权所有(C)2005,JPO&NCIPI
