Experimental passive fault tolerant control for gyroscope system

This paper is dedicated to the passive fault tolerant control of moment gyroscope. Erroneous sensor reading and actuator faults reduce the performance and may even cause the instability. As a matter of fact, the control of the gyroscope system when these drawbacks are occurred often requires the fault tolerant control design. An H_∞ robust control is designed in order to ensure the stability robustness of the system in the presence of the additive faults. Indeed, the passive fault tolerant control (PFTC) strategy is justified by its ability to maintain an acceptable performance in the presence of the noise disturbance as sensor failure. The considered technique is applied to verify the efficient performance of the PFTC controller when the occurrence of faults sensor. Simulation and experiment results are addressed to demonstrate the capability of the proposed PFTC to counteract the effect of the additive fault.
