Abstract
Description
・電極部で高調波電流および/または電圧信号を生成するために電気化学反応器の電極部を動作させるステップと、
・高調波電流および/または電圧信号の振幅および/または位相のモデルに基づく推定値を作成し、当該推定値に基づいて電気化学反応器の状態を確認するステップ。
そして、高調波電流および/または電圧信号の振幅および/または位相を推定するために再帰的な時系列ベースの方法を使用する。
信号は、高調波信号の和に基づいて推定される:
本例では、パラメータが未知の動的モデルを用い、パラメータはゆっくりとしか変化せず、確率論的プロセスノイズ(w(k))が存在すると仮定している。確率論的プロセスノイズはパラメータの時変推定を可能にする。したがって、(8)のようなノイズ処理が必須となる。
