FEEDBACK CONTROLLER DESIGN APPARATUS AND FEEDBACK CONTROLLER DESIGN METHOD

Title:

FEEDBACK CONTROLLER DESIGN APPARATUS AND FEEDBACK CONTROLLER DESIGN METHOD

Document Type and Number:

Japanese Patent JP2013254396

Kind Code:

A

Abstract:

To provide a feedback controller design apparatus and a feedback controller design method being applicable to a continuous-time piecewise affine system.

A region approximation unit 20 approximates each region of a system of a continuous-time piecewise affine system having a bias term subject to a control, with an external ellipsoid. An evaluation output setting unit weights an element of a state variable vector representing a state of the system and determines an evaluation output z=Cx for optimizing the controller. A storage unit stores linear matrix inequality. A formulation unit acquires matrices A_i, B_i, and b_i representing dynamics of the system and a matrix C for regulating the evaluation output, and generates a linear matrix inequality that is applied to the linear matrix inequality read from the storage unit, to be solved.
