This paper investigates the problem of secure fault-tolerant tracking control of a class of uncertain nonlinear systems suffering injection attacks and denial-of-service (DoS) attacks. Given the nature of denial-of-service attacks and injection attacks, we have introduced a novel approach that utilizes a switching-type state observer for ensuring control over cyber tracking and resilience against constructed to simultaneously estimate unmeasured state and compensate the actuator and sensor faults. The inherent uncertainties of the system, along with actuator and sensor faults and system disturbances, are addressed through an adaptive tracking control approach. Through the integration of adaptive control, a Fuzzy Logic System (FLS), and observer-based techniques, our method dynamically adjusts control parameters to be compatible with system uncertainties and mitigates the impact of disturbances, actuator and sensor faults, and injection attacks. Our proposed approach ensures system stability and tracking performance, providing a suitable framework for controlling the system in the presence of cyber-attacks. Simulation results on a non-linear example system demonstrate the effectiveness of the proposed method.
