    • An efficiency optimization control system of an IPMSM(Interior Permanent Magnet Synchronous Motor) using a neural network are provided to optimize an operation efficiency by outputting an optimal reference current by using a core loss compensator, a parameter estimator, and the neural network. A speed measuring unit(8) obtains a speed which is inputted to a PI(Proportional-Integral) controller from an IPMSM(Interior Permanent Magnet Synchronous Motor). The PI controller(1) receives an error between a command speed and the speed of the IPMSM and outputs a q-axis command current. A neural network(2) receives the speed from the speed measuring unit, a parameter from a parameter estimator, and the q-axis command current, and outputs a d-axis command current. A core loss compensator(3) receives the q-axis and d-axis command currents and outputs a torque component command current and a magnetic flux component command current. The parameter estimator(5) receives the torque component command current, the magnetic flux component command current, the speed from the speed measuring unit, and the q-axis command current, and outputs a parameter variation ratio. A PWM(Pulse Width Modulation) inverter(4) receives the torque component command current, the magnetic flux component command current, and a rotor position, and outputs a 3-phase current and a 3-phase voltage.

    • PURPOSE: A system and a method for controlling the speed of a permanent magnet synchronous motor are provided to appropriately manage nonlinear properties by using a variable gain proportional-integral controller. CONSTITUTION: An artificial neural network(ANN) inputs the speed of a permanent magnet synchronous motor(5) into a variable gain proportional-integral controller(1). The variable gain proportional-integral controller outputs a reference torque component current according to variations between the reference speed of the variable gain proportional-integral controller and the speed of the permanent magnet synchronous motor. A current controller(2) outputs a phase voltage reference value according to the locations of the reference torque component current, a reference magnetic flux current, and a rotor. The space vector pulse width modulation(SV PWM) inverter drives the permanent magnet synchronous motor by the phase voltage reference value.
