Discrete Feedback Systems 2.

Modern Control


Prediction models for use in MPC

MPC is a feedback law based on prediction, optimization and receding horizon implementation. The optimization is performed over open-loop predictions, which are based on a plant model. At the sampling instant k the state variable vector xk, which is assumed to be available through measurement, provides the current plant information. Then, the future control trajectory is Uk|Nc, where Nc is called the control horizon. With the given information the future state variables Xk+1|Np are predicted for Np samples, where Np, the length of the optimization window, is called the prediction horizon. The control horizon Nc is chosen to be less than (or equal to) the prediction horizon Np.

The classical control theory and methods that we have been presented in the first volume are based on a simple input-output description of the plant, expressed as a transfer function, limiting the design to single-input single-output systems and allowing only limited control of the closed-loop behaviour when feedback control is used. Typically, the need to use modern linear control arises when working with models which are complex, multiple input multiple output, or when optimization of performance is a concern. Modern control theory revolves around the so-called state-space description. The state variable representation of dynamic systems is the basis of different and very direct approaches applicable to the analysis and design of a wide range of practical control problems. To complete the design workflow, finally some introduction into system identification theory is given.
