PROBLEM TO BE SOLVED: To provide a feedback controller design device applicable to a discrete time periodical affine system, a feedback controller, and a feedback controller design method.SOLUTION: A controller design device 10 includes a setting part 20 for formulating a linear matrix inequality expression to be solved about a system for designing a controller, a controller data storage part 30 for storing an expression to be used to formulate a linear matrix inequality expression, and a calculation part 40 for calculating a stable state feedback gain within a range for satisfying the formulated linear matrix inequality expression. The setting part 20 generates a linear matrix inequality expression by applying system information represented by the discrete time format to an expression read from the controller data storage part 30. The calculation part 40 solves a convex optimization problem using the linear matrix inequality expression generated by the setting part 20 as a constraint condition with numerical calculation to calculate a state feedback gain. |
