Abstract :
We examine antiwindup internal model control with control input saturation. Past studies of antiwindup control systems have not considered the influence of disturbance. We give a new design method-antiwindup internal model control systems with unknown external signal. This method is constructed by a fusion of the internal model control structure and the disturbance observer. Using the present method, the external signals do not exert a bad influence. upon the characteristics of the control systems. A numerical example is shown.
