This paper deals with the tracking problem for constrained nonlinear systems using a model predictive control (MPC) law. MPC provides law suitable regulating linear and to given target steady state. However, when operating point changes, feasibility of controller may be lost fails track reference. In this paper, novel changing constant references is presented. The main characteristics are: (i) considering an artificial state as decision variable, (ii) minimizing cost that penalizes error...
This paper presents an experimental, Arduino based, low cost self-balancing robot developed at the University of Seville for control education. The main idea is that students can learn electronics, computer programming, modeling, and signal processing by means construction this robot. resulting model a multivariable unstable nonlinear system with non-minimum phase zero. Experimental results obtained are included to demonstrate possibilities prototype.

Abstract Model predictive control (MPC) is one of the few techniques which able to handle constraints on both state and input plant. The admissible evolution asymptotic convergence closed-loop system ensured by means suitable choice terminal cost constraint. However, most existing results MPC are designed for a regulation problem. If desired steady-state changes, controller must be redesigned guarantee feasibility optimisation problem, as well stability. Recently, novel has been proposed...
This article presents a sparse, low-memory footprint optimization algorithm for the implementation of model predictive control (MPC) tracking formulation in embedded systems. MPC has several advantages over standard formulations, such as an increased domain attraction and guaranteed recursive feasibility even event sudden reference change. However, this comes at expense addition small amount decision variables to MPC's problem that complicates structure its matrices. We propose sparse...

The main innovative point is consideration mitigation actions reduce exposure identified risks. Model predictive control used select strategic plan actions.

This paper presents a new robust MPC formulation based on nominal predictions that improves other popular formulations such as Chisci et al. (2001); Mayne (2005). As in (2001), the proposed controller ensures feasibility by means of tighter constraints, however, condition terminal constraint has been notably relaxed, leading to less conservative controllers. Another remarkable property is calculation (an approximation of) minimum positively invariant set not required, which makes its design...
Many popular approaches in the field of robust model predictive control (MPC) are based on nominal predictions. This paper presents a novel formulation this class controller with proven input-to-state stability and constraint satisfaction. Its advantages are: (i) design its main ingredients tractable for medium to large-sized systems, (ii) terminal set does not need be respect all possible system uncertainties, but only reduced that can made arbitrarily small, thus facilitating...
