Abstract
Multivariable hysteresis current controllers for three-phases inductive loads fed by means of voltage source inverters are considered in this paper. The stability of three control strategies presented in literature ([1], [2] and [3]) is rigorously analyzed by means of nonsmooth Lyapunov function and keeping into account the switching nature of the considered solutions. The main aim of this analysis is to enlighten the different robustness properties guaranteed by the aforementioned solutions with respect to typical disturbances for this kind of systems.
