Discrete-Time Integral Sliding Mode Fault-Tolerant Control with Uncertainties

摘要：

　　This paper researches fault-tolerant control for discrete-time multi-input multi-output(MIMO)linear time-invariant(LTI)systems with both matched and unmatched uncertainties.A discrete-time integral sliding mode(DISM)controller and an improved direct method for control allocation are proposed as the reconfigurable control method.Closed-loop stability with matched and unmatched uncertainties for discrete-time MIMO LTI systems with DISM is studied,and the accuracy boundaries for are determined for the final states.A spacecraft model is simulated with multi-faults,efficiency factor inaccuracies,matched uncertainties,and unmatched uncertainties,which exemplifies our FTC scheme.
