There is one warning that applies in all cases: “almost ill-posed” algebraic loops can cause problems. Simulations typically run more slowly when the system contains an almost ill-posed algebraic loop. This behavior occurs because the closer to ill-posed the equations are, the smaller the simulation steps must be to make sure that no important features in the closed-loop trajectories are missed. Explicit solutions to almost ill-posed algebraic loops are more sensitive to small perturbations to the vector ζ .
The most common way to achieve this feature is to make the input to the anti-windup augmentation equal to the difference between the input commanded to the actuator and the input supplied by the actuator to the plant. 9, and it is the architecture that will be used typically in this book. 9 The typical architecture for anti-windup augmentation. the anti-windup augmented closed-loop system. The following terminology is introduced for this system. The internal state trajectory of the closed loop is the antiwindup augmented response.
