Abstract :
This paper proposes a model predictive control of linear parameter varying systems driven by non-linear on-off control inputs. We formulate the problem as an integer quadratic programming problem. In order to ensure the closed-loop stability, we newly derive a condition for terminal cost matrices which are obtained by solving linear matrix inequalities. A numerical study is performed to verify the proposed method using a large spacecraft having rotating solar panels.
