What is it about?

Linear parameter varying (LPV) system model is useful to describe a nonlinear dynamic system. This paper deals with the problem of sampled-data model predictive control (MPC) for linear parameter varying (LPV) systems with input quantisation in practical. An input delayed dynamic model is used to construct a digital controller for continuous-time nonlinear system.

Why is it important?

To handle the quantisation and sampling, the original continuous-time system is transformed as a sector bounded input delayed system. An LMI condition of quantised MPC design is derived by constructing a new Lyapunov–Krasovskii functional.

Perspectives

The proposed sampled data model predictive control method is useful to handle the input constraint and to decide a sampling time and quantisation level of digital controller for nonlinear dynamic system.
