(詳細はtitle=Discretised PID Controllers )〕 refers to the situation in a PID feedback controller where a large change in setpoint occurs (say a positive change) and the integral terms accumulates a significant error during the rise (windup), thus overshooting and continuing to increase as this accumulated error is unwound (offset by errors in the other direction). The specific problem is the excess overshooting. == Solutions == This problem can be addressed by: * Initialising the controller integral to a desired value * Increasing the setpoint in a suitable ramp * Disabling the integral function until the to-be-controlled process variable (PV) has entered the controllable region * Preventing the integral term from accumulating above or below pre-determined bounds * Back-calculating the integral term to constrain the process output within feasible bounds. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Integral windup」の詳細全文を読む スポンサード リンク
