FEMPC - Fast explicit modell predicitve control


Ref.-No. 5248

Model predictive control (MPC) has gained in importance in recent years in many industrial applications. Typical implementations are based on solving a numerical optimization problem in each clock cycle. In certain applications it is possible to dispense with numerical optimizations and instead to calculate an analzyic law of control with parametric programming methods ("explicit MPC").

Keywords: Modellprädiktive Regelung, Regelungstechnik, Mikroprozessor, Mikrocontroller, Regler, Model predictive control, microprocessor, micro Controller

The invention implements explicit MPC control laws on a massively parallel reconfigurable hardware (field programmable gate arrays or similar). The degree of parallelization depends only on the hardware resources and is customizable. A microprocessor, as used in the classic MPC, is not needed. The circuit is ideal for embedded controllers due to its compact size, low power consumption and high clock rates. In addition, clock frequencies can be achieved that are well beyond those feasible with optimization-based MPC. In contrast to many optimization-based implementations, real-time capability can be guaranteed in the strictest sense.

Competitive Advantages

  • High control speed
  • Real-time capability
  • Compact
  • Flexible
  • Energy saving

Commercial Opportunities

The invention can be used in all applications for which explicit MPC laws are available. The circuit is fast and very compact.
