The analytical co-design strategies of receding horizon estimation (RHE) and control (RHC) have been proposed in this brief for the general applications of power converters. A typical two-level power module with $LC$ filter system is demonstrated for the estimation and control implementation. The proposed analytical co-design procedures include: 1) system state space modeling; 2) receding horizon configuration/setup; 3) application of RHE–RHC for various interfaces; and 4) parametric analysis. The proposed strategies have been validated for the energy conversion applications of grid-connected dc/ac inverter and resistive load dc/dc converter. The advantages include: 1) reduced sensor cost with accurate estimation; 2) improved transient performance with receding horizon-based algorithms; and 3) reconfigurable RHE and RHC software unit for wide applications. The experimental test results verified the proposed methods.
