A new periodic multirate model reference adaptive controller for possibly non stably invertible plants. (English) Zbl 0933.93049
The paper deals with the model reference control of linear continuous-time systems with unknown parameters. The authors explore the possibility of extending the multirate-input controller (MRIC) approach proposed recently by the first author and P. N. Paraskevopoulos [ Proc. 2nd E.C.C., Groningen, The Netherlands, Vol. 3, 1648-1652 (1992)] to control linear time-invariant plants with unknown parameters. On the basis of the MRIC approach, which is considered as an alternative to standard dynamic compensation, the solution to the model matching problem is reduced to the solution to a non-homogeneous algebraic matrix equation rather than a polynomial diophantine equation required in the standard indirect model reference adaptive technique. Finally, persistency of excitation of the continuous-time plant under control is ensured without special assumption on the reference signal and the only a priori knowledge required is controllability and observability of the continuous and sampled system and known order.
