Parameters for the discretized model Actuator or control surface failures were modeled by multiplying the respective column of Bu1 and Du1 by a factor between zero and one where zero corresponds to a total or complete actuator failure or missing control surface and one to an unimpaired normal actuator control surface. Likewise for sensor failures where the role of Bu1 and Du1 is 440 Discrete Time Systems replaced with C1. It was assumed that the damage does not affect the fuel cell system dynamic matrix A1 implying that the dynamics of the system are not changed. Let sampling period T 1s.
