- Abstract
An output‐feedback sliding‐mode controller is proposed for multivariable uncertain systems with unknown time‐varying state delays and unmatched non‐linear terms. The non‐linearities are allowed to depend not only on the system output, but also on its unmeasurable state, and can be polynomial. This scheme is based on model‐reference unit vector control under a mild Hurwitz condition for the high‐frequency gain matrix. To achieve global stability properties, the amplitude of the control signal is given by a norm observer for the unmeasured state. For the first time, the design of norm observers is applied to a class of time‐delay systems. This approach guarantees finite‐time convergence of the output‐tracking error to zero. Simulation results illustrate the application of the developed control scheme.
