In its most general aspect, the present invention relates to a method for creating digital circuits of a feedback control system that implements an approximation technique for Model Predictive Control (MPC). In addition to that, circuit architectures of the aforesaid control system are also described.

In this paper we introduce a digital architecture implementing piecewise-affine functions defined over domains partitioned into polytopes: the functions are linear affine over each polytope. The polytope containing the input vector is found by exploring a previously constructed binary search tree. Once the polytope is detected, the function is...

This paper presents a low-cost method for online monitoring the inductor behavior in a switch-mode power converter. The method exploits the embedded electronics already available for the converter control, typically a microcontroller. By properly sampling the inductor voltage and current, the method allows estimating on-line the inductor's...

Understanding mixing processes that occur in the human vitreous chamber is of fundamental importance due to the relevant clinical implications in drug delivery treatments of several eye conditions. In this article we rely on experimental observations (which demonstrated that dispersion coefficients largely dominate diffusive coefficients) on a...

This brief is concerned with the problem of mitigating the "curse of dimensionality" in the piecewise-affine simplicial approximation of multivariate model predictive control (MPC) functions by resorting to nonuniform domain partitions, in view of their implementation in high-speed embedded digital architectures. Two dual strategies are used to...

This paper describes a MATLAB Toolbox for the integrated design of Model Predictive Control (MPC) state-feedback control laws and the digital circuits implementing them. Explicit MPC laws can be designed using optimal and sub-optimal formulations, directly taking into account the specications of the digital circuit implementing the control law...

In this paper we analyze some properties of a recently proposed model of hysteresis and creep (related to a circuit model, whose only nonlinear element is based on a power law) and compare it with the well-known Kuhnen's model. A first qualitative comparison relies on the analysis of the behavior of the elementary cell of each model. Their...

In this paper a switched Model Predictive Control strategy is applied for the speed regulation of a powertrain system composed of an electrical motor connected to a rotating load through an elastic shaft and a gear, which introduces backlash. The system is described through a piecewise-affine model and a different control law is designed for...
