Regularization of components switching for multideminsional discontinuous control in a real sliding mode

The design of vector algorithms for discontinuous (relay) control in multidimensional systems on the basis of the concepts of instantaneous and average control is considered. Control algorithms are offered characterized by switching regularization of the discontinuous control components due to a special choice of switching surfaces. By an example of current control for a three-phase load fed from a self-commutated voltage inverter, the paper shows that the approach proposed ensures high dynamic performance and accuracy along with minimal switching losses and the compliance with electromagnetic compatibility requirements.
