Title:
CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2017016391
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve the problem that in the case of finite time settling control in homogenous control, oscillation is deteriorated when an error is small or follow-up performance is deteriorated when an error is 1 or greater.SOLUTION: A control device 3 comprises: an error calculation unit 31 for calculating an error in the present value of a control object with respect to a host command value; a homogenous order acquisition unit 33 for acquiring a homogenous order in accordance with the error; an arithmetic unit 34 for performing an exponential arithmetic on the error that corresponds to the homogenous order so that homogenous control is achieved; and a command value calculation unit 36 for calculating a low-order command value from the arithmetic result. The homogenous order is set to 0 in a small range and a large range of errors. As a result, it is possible to suppress an increase in oscillation in the small range of errors, as compared with finite time settling control, and to improve convergence in the large range of errors.SELECTED DRAWING: Figure 7
