Robust Feedback Model Predictive Control of Sea Wave Energy Converters

Different Model Predictive Control Approaches for Controlling Point Absorber Wave Energy Converters

Ocean wave energy is a promising renewable energy source that can be converted into useful electrical energy using wave energy converters (WECs). In order for WECs to become a commercially viable alternative to established methods of energy generation, operating the WEC in an optimal fashion is a key task. Thus, model predictive control (MPC) is an encouraging control method that exploits the e...

Robust output feedback model predictive control of constrained linear systems

This paper provides a solution to the problem of robust output feedback model predictive control of constrained, linear, discrete-time systems in the presence of bounded state and output disturbances. The proposed output feedback controller consists of a simple, stable Luenberger state estimator and a recently developed, robustly stabilizing, tube-based, model predictive controller. The state e...

Model predictive control of a sea wave energy converter: a convex approach

This paper investigates model predictive control (MPC) of a sea wave energy converter(WEC). A novel objective function is adopted in the MPC design, which brings obvious benefits: First, the quadratic program (QP) derived from this objective function can be easily convexified, which facilitates the employment of existing efficient optimization algorithms. Second, this novel design can trade off...

Robust Model Predictive Control

The robust control problem concerns to the control of plants that are only approximately known. Usually, it is assumed that the plant lies in a set of possible plants and this set can be quantitatively characterized. It is sought a control design that assures some kind of performance, which includes stability, for all the members of the family of candidate plants. Robust control theory usually ...
