Title:
制御装置および制御方法
Document Type and Number:
Japanese Patent JP4027935
Kind Code:
B2
Abstract:
A control unit and a control method are disclosed. First and a second changing units (316 and 318) change impedances of two or more first and second components within a predetermined first and second ranges, respectively, the first and the second components affecting an output signal. An evaluation function value calculating unit (311) calculates an evaluation function value that is dependent on the impedances of the first and the second components. A gradient vector calculating unit (312) calculates a gradient vector based on the difference between the evaluation function values before and after the impedance change of the second components. Based on the gradient vector, impedance of each of the first components is changed such that the evaluation function value takes a desired value.
