The anti-windup measure helps to ensure that the integral component does not grow too much causing the controller to lock if it has been held at a control limit too long.

Anti-windup measures are only performed for an active I component of the controller. Limits for the anti-windup measure are by default the manipulated variables defined limits (yao, yau) of the controller (dyaw = 0). The parameter dyaw can be used to either increase (dyaw > 0) or decrease (dyaw < 0) the limits with regard to the control limits (yao, yau).

Through displacement of the anti windup defined control limits in relation to the control limits (in particular with very noisy signals), the manipulated variable y can be stopped from repeatedly 'jumping away' from the control limit (D component effect to disturbances) and subsequently returning to the limiting position (I component effect with system deviation xd ≠ 0).

If the control limits are to be simultaneously effective for the anti-windup measure and the manipulated variable Y, select the parameter dyaw = 0.

By utilizing negative dyaw values, anti-windup limits can be kept smaller than control limits (useful for anti-windup halt).

This anti-windup measure disregards the D component, to avoid the capping of the D component peaks through the anti-windup measure. The anti-windup-reset measure corrects the I component such that: AWMIN ≤ YP + Z + YI ≤ AWMAX.

This anti-windup measure only considers the I component. When anti-windup halt and I component are enabled, the anti-windup halt measure corrects the I component such that: AWMIN ≤ yi ≤ AWMAX.

The parameters vwh and vyh represent velocity limiters for the manual values wh and yh. A 0 value disables the functionality of the corresponding velocity limiter (vwh = 0 or vyh = 0, respectively). The wh and yh values are then utilized without delay.
