Tracking Control for Constrained Nonlinear Systems

Abstract

A new input-output constrained (IOC) model-free adaptive tracking control (IOC-MFATC) problem for nonlinear constrained systems against DoS attacks is studied in this paper. Firstly, considering malicious attacks in the network, an attack compensation mechanism is introduced to compensate for DoS attacks. And due to the restriction of practical physical conditions, the IOC strategy is put forward to guarantee the equipment security. Then, for the nonlinear system with unknown model, the new IOC-MFATC algorithm designed with the input and output data can guarantee the safe tracking control problem. Finally, the simulation results demonstrate the effectiveness of the presented algorithm.
