SIMPLE ALGORITHMS OF ADAPTIVE AND ROBUST CONTROL OVER A CLASS OF LINEAR TIME-VARYING OBJECTS

Annotation

Two simple solutions to the problem of adaptive state-feedback control are proposed for a class of time-variant linear objects. State matrix is presented in the low triangular form. The control design is based on standard pole placement approach with variable average radius of roots distribution. The radius is generated by robust adaptation algorithm in the first solution and by nonlinear static feedback in the second one. The control provides the boundedness of all signals in the closed-loop system and exponential convergence of the object output signal to output signal of reference model.
