摘要： Inverter control method and apparatus which are immune to the influence of load disturbance and detection noise and permit stable minimization control of motor current, in order to attain high efficiency of an AC motor and of an inverter adapted to drive the same. A memory group is provided having a plurality of sets of memories for storage of data pieces representative of exciting current commands standing for manipulated variables and data pieces representative of motor currents standing for controlled variables. An upper limit value (IDUP) and a lower limit value (IDLW) defining a fluctuation region of the exciting current command are determined so that an exciting current command data piece corresponding to a motor current data piece which is the smallest of all the current data pieces in the memory group falls within the fluctuation region. The fluctuation region is determined so as to minimize the motor current, the exciting current command being fluctuated within the fluctuation region.

摘要： A trip-resistant frequency control inverter which prevents an overcurrent and overvoltage by frequency control of a motor. Such arrangement provides for generating an accelerating or decelerating rate from the output from a fuzzy controller, which inputs the difference between limiting values and detected values and their changes. The arrangement also provides at the time of acceleration a control which automatically generates an accelerating rate which maintains the current in the vicinity of the limiting value, and a normal acceleration part which adjusts the set accelerating rate. The arrangement further provides at the time of deceleration a control which automatically generates a decelerating rate which maintains the current and voltage in the vicinity of their limiting values, and a normal deceleration part which adjusts the set decelerating rate. Further, the arrangement provides during a steady state operation a control which automatically determines the accelerating or decelerating rate which maintains the current in the vicinity of the limiting value, and wherein the two control parts for automatic and normal operation are selectable by an operator.

Operation management specifications of the main circuit are fixed independently of operation management specifications of the input/output interface.
