A slip frequency type driving control apparatus includes a detector for detecting an input current and an input voltage to an induction motor, a calculating unit for calculating a rotor flux and a torque current of the induction motor, a neural network for outputting an excitation current command value and a slip frequency command value, and a vector control unit for performing vector control for the induction motor. The neural network receives a rotor flux command value, a torque current command value, a calculated rotor flux value, and a calculated torque current value, performs learning on the basis of a back-propagation law using signals output in correspondence with these inputs, and outputs an excitation current command value and a slip frequency command value. The vector control unit detects the torque current and the excitation current on the basis of the output slip frequency command value from the neural network and controls the induction motor in accordance with a deviation between the detected excitation current value and the excitation current command value and a deviation between the detected torque current value and the torque current command value.
