<P>PROBLEM TO BE SOLVED: To stably supply the torque being the output of a motor. <P>SOLUTION: The stable torque can be obtained from a motor since this current controller can make a current flowing to the winding a desired current by modulating the application start timing command value θon* of a rectangular waveform voltage that an inverter 2 adds to the winding wound on the stator of a motor, or the application finish timing command value θoff* of a rectangular waveform voltage, or both by the difference between a sampling value is obtained by sampling the output of a current sensor 3 for outputting the value of the current flowing to the winding wound on the stator of the motor 4 at the angle θs of a rotor being obtained from an angle position sensor 5 and the expected value ie of the instantaneous current at the angle θs of the rotor, thereby modulating the waveform of rectangular waveform voltage. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
