DYNAMIC CURRENT CONTROL FOR IMPRESSING THE TORQUE IN 3-PHASE DRIVES WITH PULSE CONTROLLED INVERTER

The principle of field orientation allows the decoupled control of tor que and rotor flux. By means of a fast secondary current control, it i s possible to realize an undelayed impressing of torque for the superi mposed speed control. The article continues efforts for a standard sol ution of this problem and shows that the new current vector and curren t state feed back controller with dead-beat behaviour can be applied w ith good results in field synchronous coordinates as well as in stator fixed coordinates.
