PROBLEM TO BE SOLVED: To improve the safe side failure ratio by reducing such a possibility that a dander side failure occurs in a control system due to such a failure that switching cannot be performed in a switching mechanism.SOLUTION: In a control controller comprising: a main channel 201 and a backup channel 202 which generate control signals for controlling an actuator; a channel failure detection part 203 which detects failures of both channels 201, 202; and a switching mechanism 204 which switches the control signals output from both channels 201, 202 to output them to an output interface 215, the switching mechanism 204 comprises: a main switch 213 and a backup switch 214 which switch connection states between both channels 201, 202 and the output interface 215; a switching control part 212 which switches connection states of both switches 213, 214; and a switch failure detection part 211 which detects the failures of both switches 213, 214.SELECTED DRAWING: Figure 2
【課題】本発明の目的は、切替機構の内部で切替できないという故障によって、制御系システムが危険側故障になることを低減し、安全側故障割合を向上させることにある。【解決手段】アクチュエータを制御する制御信号を生成するメインチャネル201及びバックアップチャネル202と、両チャネル201,202の故障を検出するチャネル故障検出部203と、両チャネル201,202が出力する制御信号を切替えて出力インタフェース215に出力する切替機構204とを備えた制御コントローラにおいて、切替機構204は、両チャネル201,202と出力インタフェース215との接続状態を切替えるメインスイッチ213及びバックアップスイッチ214と、両スイッチ213,214の接続状態を切替える切替制御部212と、両スイッチ213,214の故障を検出するスイッチ故障検出部211とを有する。【選択図】 図2
