The authors suggest an indirect adaptive linear quadratic (LQ) optimal tracking of continuous-time linear time-invariant single-input, single-output systems using multirate-output controllers. Using the proposed technique, the adaptive LQ problem is reduced to the determination of a fictitious static state feedback controller. Persistency of excitation of the plant under control is provided without making any assumption on the existence of special convex sets to which the estimated parameters belong or on the coprimeness of the polynomials describing the ARMA model, as compared to known adaptive LQ optimal control schemes.
