Fault‐tolerant fixed‐time prescribed performance control of MEMS gyroscope

This paper investigates a fault-tolerant fixed-time prescribed performance microelectromechanical system gyroscope using the adaptive backstepping method. The control protocol is designed such that not only robust to even extremely harsh conditions of disturbance and actuator faults but also its settling time are user-adjustable. Also, itself along with external disturbances assumed be uncertain. Two case studies have been analyzed; controller in presence very severe while uncertain faults, comparison between finite-time this model terms their convergence rate. First, dynamics derived, error defined for analysis. Then, method, estimations uncertainties, algorithm converge errors small set near zero rate after which stability verified via Lyapunov theory. In end, simulation example presented each study represent efficacy proposed scheme.
