Control system design equipment and test equipment equipped with it

摘要

PROBLEM TO BE SOLVED: To provide a control system design device capable of easily designing a control system for H∞ control. A control system design device 6 has a design transfer function acquisition unit 61 that corresponds to a control target P and acquires a design transfer function used for control design of a control system, and two types of weights used in H∞ control. The weight function acquisition unit 62 for acquiring the functions Ws and Wt, the H∞ control transfer function acquisition unit 63 for acquiring the H∞ control transfer function using the design transfer function and the two types of weight functions, and the above. A stability determination unit 64 for determining whether or not the transfer function of the H∞ control satisfies a predetermined condition is provided. In the control system design device 6, the weight function acquisition unit 62 changes the weight function and H until the stability determination unit 64 determines that the transfer function of the H∞ control satisfies the predetermined condition. The ∞ control transfer function acquisition unit 63 acquires the H∞ control transfer function using the design transfer function and the modified weight function. [Selection diagram] Fig. 1
