Abstract

A concept of decoupling control in the strategy of the speed regulation of the squirrel cage induction motor with controlled voltage source is represented. The decoupling control intends to cancel out the cross terms between the secondary flux and the secondary current. Three necessary and sufficient conditions for the decoupling control are offered that correspond to taking into account the effect of the primary impedance in the control strategy. Phase lead compensation with the slip frequency control allows the realization of the decoupling control, which is found to be an extension of both the conventional vector control and the constant volts/hertz control. Numerical and experimental results are also shown.
