Sensor and actuator attacks can alter the truth values of vehicle states and control input through false data injection, leading to performance degradation. In this paper, secure control of vehicular platoon control systems (VPCS) subject to joint sensor-actuator attacks, and the unknown disturbances is investigated. First, a novel adaptive sensor fusion algorithm is designed to estimate the actual position with smaller fusion errors. Subsequently, a predefined-time extended state observer (PTESO) is further constructed based on the estimated position to recover the continuous-time states (i.e., velocity and acceleration) and disturbances accurately within a user-defined settling time. Then, a variable exponent predefined-time sliding mode controller (VPTSMC) with few design parameters is developed to guarantee the predefined-time stability of the platoon system, namely string stability and individual vehicle stability. Meanwhile, the singularity phenomenon is also avoided. Finally, a serious of simulations are carried out to show the effectiveness of the suggested control scheme.
