Robust Asymptotic Tracking Controller Design for Linear Systems with Uncertain Parameters and Unknown Delays

Taking into consideration linear uncertain systems with delay, the paper proposes a new method of designing a robust asymptotic tracking controller by adopting the linear matrix inequality (LMI) approach. The designed controller is uncertain for control input matrix, state input matrix and controlled output matrix, and has some systems with delay with state delay, and all these make the output of the system approximate tracking external reference signals. For all allowable parameter variations and delays, the systems are internally stable and their outputs asymptotically track the command reference input. The asymptotic tracking is proofed by Lyapunov function. The results of Matlab simulation show that this approach is feasible.
