Abstract:
The finite-time stable predictive control problem for a class of discrete-time linear time-invariant systems is studied. The concept of finite-time stability is introduced into predictive control, and the relationship between finite-time stability and predictive control is established by the state feedback.The minimization optimization problem in finite time domain is transformed into a constrained problem with linear matrix inequalities by constructing the Lyapunov function. The sufficient conditions for the existence of state feedback control rate are given by using linear matrix inequalities. The numerical simulation results show the effectiveness of the proposed method.
