摘要：AbstractIn this paper, a new switched control strategy for three-phase AC-DC power converters, also known as controlled rectifiers, is proposed. More specifically, a switching function is determined to command the converter switches at each instant of time assuring global asymptotic tracking of a desired reference trajectory, which is related to a constant output voltage and sinusoidal phase currents. This is generally a desired situation for AC-DC power converters as it can ensure unitary power factor and rectified steady-state D C voltage simultaneously. The proposed switching function must also assure a guaranteed performance cost. The design conditions are based on a Lyapunov function, which is dependent on the electrical angle, and are expressed in terms of linear matrix inequalities (LMIs). Simulation results put in evidence the effectiveness of the proposed methodology and motivate future related works.
