フィードバック制御方法、及びモータ制御装置
Document Type and Number:
Japanese Patent JP6979330
Kind Code:
B2
Abstract:
An objective of the present invention is to provide a feedback control method involving a lag compensator appropriate for implementation and a motor control device using said feedback control method such that computation costs can be reduced for the lag compensator which is capable of reducing step disturbances added to the input end of a plant without leaving errors even if the plant has a pole at the origin. To achieve the objective, provided is a lag compensator 1 which comprises a feedback controller 1, a filter 1, and a model of a plant, receives the output of a feedback controller 2 and a response by the plant as input, and outputs a feedback signal for the controller 2, wherein the lag compensator 1 produces as a manipulation quantity 1 a signal obtained by adding the output of the controller 1 and the output of the controller 2, subtracts an output of the model of the plant in response to the manipulation quantity 1 from the response of the plant to obtain an error signal 1 to be used as the input for the controller 1, and adds a signal resulting from passing the error signal 1 through the filter to the response of the nominal plant model to the manipulation quantity to produce the output signal.
