Servo control apparatus

Abstract

将扰动抑制系统并入伺服控制装置中。在该扰动抑制系统中,因扰动估计误差而被引入到目标设备的输出中的分量e,在具有与设备误差(该设备误差为目标设备和设备模型之间的传递特征的差异)的大小相对应的频率特征的扰动抑制控制器中被放大,并且放大的分量e被反馈回控制输入。
A disturbance suppressing system is incorporated in a servo control apparatus. In the disturbance suppressing system, a component e introduced in an output of a target plant due to a disturbance estimate error is amplified in a disturbance suppressing controller having a frequency characteristic corresponding to a magnitude of a plant error, which is a difference in transfer characteristics between the target plant and the plant model, and the amplified component e is fed back to a control input.
