| Abstract: | A real time adaptive current controller for a drive system with a PWM inverter fed permanent magnet synchronous motor is presented. The current control scheme proposed is based on predictive current control but with an identification algorithm added in order to compensate for the inaccuracy of the motor parameters. The parameters of armature inductance and flux linkage are identified by comparing the difference between the outputs of the calculation model and the actual motor. A DSP based implementation scheme is presented. Experimental results are given. |
