摘要： PROBLEM TO BE SOLVED: To supply a phase current accurately by varying the magnitude of a first commutative applying current from the original magnitude toward a second commutative applying current. SOLUTION: A first current path passes through upper and lower drivers 14, 22 while second current path passes through upper and lower drivers 18, 20. The current flowing through an regulative detection transistor 32 is regulated such that the current flowing through the second current path will be substantially equal to the current flowing through the first current path. Since the ration between a mirror device (detection transistor 32) and a power device (upper and lower drivers 14, 18, 20, 22) can be regulated in every chip using the regulative detection transistor 32, current of each phase can be measured with high accuracy.

摘要： PURPOSE:To provide an automatic field current measuring method of an automatic controller for a DC shunt motor optimally employed in the making of a rotational, speed vs field current table for allowing high response stabilized rotational speed control of the DC shunt motor. CONSTITUTION:A predetermined armature voltage is fed to a motor 6 under no-load and the field winding 6F of the motor is subjected to supply control through an amplifying function 4 equipped with an auto-set rotational speed integrating function. Rotational speed is controlled automatically while varying the set value of rotational speed automatically at a predetermined pitch. Field current is measured automatically for each rotational speed and the field current value for each set rotational speed is recorded sequentially and automatically.

摘要： PURPOSE:To obtain a verification and inference result quickly by a method wherein inference information in the past is utilized in an inference in the next operation and onward. CONSTITUTION:When the state of a fault is found out from control data, an inference execution means 25 selects all knowledge modules having a rule regarding the fault from a knowledge module group in a knowledge base 24 and executes an inference. At this time, when the value of the fault is required, a means value or a maximum value which has been computed and judged from a data storage part 23 is read out, and the inference is executed until a rule adapted to the rule of a knowledge module is found out. Then, information on the process of the inference is displayed on a verification-result output part 16 via a verfication processing means 26. In addition, an inference result is displyed on an inference-result output part 15, and it is converted into a format which can be read out by an expert-system-construction-tool part 14, and it is stored in an inference information file (IF) 31. Such a series of information execution processing operations is repeated, and an inference result obtained every time is stored in the IF 31.
