Abstract:

This paper presents a model predictive voltage control (MPVC) method for the single-inductor multiple-output (SIMO) dc-dc converter. The proposed MPVC method is able to solve the cross-regulation problem, which is a critical issue in SIMO dc-dc converters. The design of the proposed method including augmented state-space model, cost function, enumerated algorithm, and constraints for the SIMO dc-dc converter is discussed. Simulation for the influences of predict horizon N P , control horizon N C , and Lagrange multiplier λ on the voltage ripple is conducted to guide the control parameters' setting for hardware implementation. Steady-state operation and dynamic performance of the proposed MPVC method are conducted in simulation and experiment based on the single-inductor dual-output (SIDO) buck converter to verify the proposed MPVC method. In addition, the comparison between the proposed method and state-of-art methods for the SIMO dc-dc converters is presented. Simulation and experimental results demonstrate that the MPVC method guarantees low cross regulation for the SIMO dc-dc converter in continuous-conduction mode (CCM) and has a fast response speed to variations in load and reference.
