Abstract

In recognition of problems associated with existing non-constraints maximum power point tracking (MPPT) algorithms such as slow convergence speed and losses due to oscillations at steady-state, this paper presents a constraints-based extremum seeking control CB-ESC for thermoelectric generator (TEG) systems. This work also describes the practical implementation of a CB-ESC for MPPT using an in-house test rig. The experimental set-up utilises dSPACE for hardware in the loop (HIL) simulation. Perturb and observe (P&O) and standard extremum seeking control (ESC) algorithms serve as benchmark controllers. Compared to the benchmark controllers, CB-ESC has achieved better performance in both transients and steady-state. Limitations and challenges of practical implementations of the CB-ESC is explained in this paper. MATLAB/Simulink software is used for the development of control strategies.
