摘要:AbstractIn the present paper, we discuss control design for a pneumatic isolation table including different time delays that are dependent on control input polarity. For such a plant, the control design problem is essentially that for a switched system. In the present paper, we first describe a model of the plant. The plant is represented by a linear system in which the input matrix in the state-space representation changes depending on the input polarity. Next, we discuss state-feedback control design for the system. A controller is obtained by solving an optimal problem, which guarantees stability as well as control performance, using linear matrix inequality (LMI) techniques. Finally, the control performance achieved by the proposed method is verified through numerical simulations.
