Composite Adaptive Antidisturbance Control for Discrete-Time Switched System

الملخص EN

A novel composite adaptive antidisturbance controller is developed for a class of discrete-time switched system.

First, two composite adaptive observers are proposed to estimate the external disturbances and unknown parameters, respectively.

Then, based on the estimation values, a composite adaptive antidisturbance controller is constructed, which can guarantee system has a good antidisturbance performance.

A solvable sufficient condition is presented by using linear matrix inequalities (LMIs).

Finally, a numerical example is shown to demonstrate the effectiveness of the proposed control approach.
