摘要
A discrete-time current control method is specified for an invertor-fed asynchronous motor, using rotor-flux-related components with the required value of the current being preset in a pulsed manner, the actual value of the current being detected by taking samples synchronised to the same time clock, with the actual value being processed, and with a control variable, which is provided by the controller synchronised to the same time clock, for the invertor. In the case of this method, the parameters to be set are reduced to a minimum. These parameters furthermore directly characterise the behaviour of the closed control loop and are independent of current motor parameters. The matching to the current motor parameters is carried out automatically by the method. IMAGE
