From (7), we can see that the first fault component (I) is always smallerthan the control input , i.e., (I) < . It means the controlinput u = can be increased freely up to its maximum valuewithout any bounds. The remain issue is to get the bound ofthe bias fault . The assumption on the bound of the biasfault is generic and has been widely utilized in the design of FTC (see [58]-[60]). This condition states that the FTC is designed for the situation where the system is not “exploding”.It means the Lipschitz condition is practically satisfied in the considered operational region (see [61]).
