    • A plant controller includes a feedback controller configured to calculate a control input provided to a plant so that a control output of the plant matches a target value. The feedback controller includes a controller transfer function that is a transfer function of the feedback controller. The controller transfer function is expressed by a product of an inverse transfer function of a transfer function of a control target model obtained by modeling the plant and a disturbance sensitivity correlation function defined using a sensitivity function. The sensitivity function indicates sensitivity of a disturbance to be applied to the plant with respect to the control output. The sensitivity function is defined by using a response characteristic parameter that indicates a response characteristic of the plant.
    • 工厂控制器包括反馈控制器,其被配置为计算提供给工厂的控制输入,使得设备的控制输出与目标值匹配。 反馈控制器包括作为反馈控制器的传递函数的控制器传递函数。 控制器传递函数由通过对工厂进行建模获得的控制目标模型的传递函数的反向传递函数和使用灵敏度函数定义的干扰敏感度相关函数的乘积表示。 灵敏度功能表示相对于控制输出对工厂施加扰动的灵敏度。 灵敏度函数通过使用指示工厂的响应特性的响应特性参数来定义。
