主　　题：Control systems design methodology 

摘      要：The issue separating our original paper [1] and the comments of Mantz and De Battista [2] lies in the criteria for the evaluation of an antiwindup (AW) method. Mantz and De Battista suggest that when evaluating the performance of an AW algorithm, the response of the system with AW compensation must be compared with the linear response. That is, it is claimed that the quality of an AW technique is best determined by comparing the response of a nominal proportional-integral-derivative (PID) control law in closed loop with a plant that does not have an input saturation constraint with the closed-loop response of an AWPID control law in closed loop with a plant that does have an input saturation constraint. While this criterion is valuable, it is only one of several design issues that are faced by a control system designer. Other design issues include the following: 1) closed-loop stability; 2) transient response; 3) disturbance rejection; 4) closed-loop robustness of stability and performance to modeling uncertainty; 5) required control effort; 6) controller topology (implementation concerns such as simplicity of tuning/design parameter selection).
