Constrained Optimal Control of the Step-Down DC–DC Converter

Discrete-Time Tool for Stability Analysis of DC Power Electronics-Based Cascaded Systems

“…Therefore, classical tools cannot accurately study the stability margin, neither the dynamic behavior of the system. Discrete-time models are a reliable solution to study the dynamic behavior of switching converters [33][34][35][36][37][38][39]. The discritization approach has been mainly used for control design.…”

Adaptive reference model predictive control for power electronics

“…Therefore, it is necessary to compensate the control set such that this error can be mitigated. Several schemes have been proposed to overcome such steady-state errors [10]- [12]. In [10], a Kalman filter is added with MPC to account for unmeasured load variations and to achieve zero steady-state errors.…”

“…Several schemes have been proposed to overcome such steady-state errors [10]- [12]. In [10], a Kalman filter is added with MPC to account for unmeasured load variations and to achieve zero steady-state errors. In [11], MPC with long horizons carry the benefits of lowering the total harmonic distortion (THD) of the output as well as reducing the steady-state residues.…”

“…In [12], MPC with integrator is proposed to reduce the steady-state errors both at the sampling instant and during the intersampling. To integrate the merits of the strategies proposed in [10]- [12] and also extensively simplifying the algorithm, a method that adaptively compensate the control set to mitigate the steadystate errors, which is achieved through the application of trajectory-based control [15]- [18] to the existing framework of MPC, is proposed in this paper. This method is known as adaptive reference model predictive control (ARMPC).…”

Implementation of Robust Prediction Observer Controller for DC-DC Converter

“…Furthermore, the constraints in the design of controller results due to the duty cycle which is bounded between zero and one. This problem can be solved by modelling the dc-dc converters using state space averaging technique [5]. By using this technique, the converter can be described by a single equation approximately over a number of switching cycles.…”
