MATLAB/Simulink Implementation of MAB Converter with DPS Modulation, Closed-Loop Voltage and Current Control

Project Description:

I am looking for an experienced MATLAB/Simulink expert to develop a detailed simulation model of a Multi-Active Bridge (MAB) DC-DC converter using the Double Phase Shift (DPS) modulation scheme.
The system will consider two ports as sources and two ports as loads. The project involves the following tasks:

Scope of Work:

1. Closed-Loop Controller Design:
- Implement an Open Loop/closed-loop voltage and current control system to regulate output voltage and track reference power.
- Design appropriate controllers (e.g., PI or state-feedback) for dynamic response tuning.
- Linearize the system to design a controller.
- Use any suitable PI control method to compute Kp and Ki values for decoupling power and handling unknown system parameters.

2 Power Flow Modeling
- Apply Double Phase Shift (DPS) modulation to control power flow between ports.
- Calculate and derive equations for power transfer, duty cycles, and phase shifts (ϕ).

3. MATLAB Function Block Logic:
- Develop custom logic in MATLAB Function blocks to implement switching signals and DPS scheme.
- Ensure compatibility with closed-loop feedback control.

4. Deliverables:
- Complete Simulink model with user-defined parameters for easy tuning.
- MATLAB scripts/functions used for controller design and calculations.
- Clear documentation or brief explanation of the system operation and implementation logic.

Requirements:

- Strong knowledge of power electronics and DC-DC converter topologies (especially MAB and DAB).
- Proficiency in MATLAB/Simulink modeling and custom MATLAB function blocks.
- Experience with modulation schemes and control system design.
