When FPGAs Meet Regionless Explicit MPC: An Implementation of Long-horizon Linear MPC for Power Electronic Systems

Abstract: This paper presents a novel real-time implementation of linear model predictive control (MPC) schemes based on region-less explicit MPC (RL-EMPC). RL-EMPC is a recently proposed explicit MPC solution for achieving a low memory footprint compared to other explicit MPC methods. Thus RL-EMPC can effectively handle systems with high sampling rates even for large-size MPC problems, i.e. systems with many states and/or constraints. An architecture for an implementation on an FPGA device is presented and validated wi… Show more

“…Another study implemented Finite Control Set-MPC for power electronic systems using FPGAs, considering resource utilization and performance evaluation [48]. The deployment of long-horizon linear MPC on FPGAs was proven for regulating different power electronic systems in research [49]. Collectively, these papers illustrate the successful incorporation of MPC into FPGAs across a spectrum of control applications.…”

“…Long prediction horizon brings many benefits to MPC, but the computational burden of MPC increases dramatically with longer prediction horizons. However, recent discoveries in efficient optimisation problem-solving and advances in computational power of embedded systems facilitate a realtime implementation of long-prediction horizon MPC at high sampling rates [12], [13]. Therefore, the proposed method is not just confined to theory or simulation but also can be applied in real converter systems.…”

“…Then, the process of solving the underlying optimization problem can be conducted offline, resulting in a piecewise affine function of the optimization parameters. The proposed MPC formulation has a relatively values are given in section VI-C. A real-time implementation at a high switching frequency can be achieved in this size range of region numbers using an FPGA device as demonstrated in [14]. In the following section, it will be shown how the possible filter design space can be extended based on the proposed MPC.…”
