Adaptive decoupling of linear systems using multirate generalized sampled-data hold functions. (English) Zbl 0832.93033
Summary: An indirect adaptive controller synthesis algorithm is derived for the decoupling of linear multivariable time-invariant systems with unknown parameters using multirate generalized sampled-data hold functions. Such controllers contain a multirate sampling mechanism with different sampling period at each system input and two periodically varying modulating matrix functions. The algorithm proposed estimates the modulating functions on line, and ensures persistent excitation of the continuous-time plant without making any assumption on the reference signals. The only prior knowledge needed is the minimality of the continuous and sampled system, known order, and a set of structural indices, namely the locally minimum controllability indices of the continuous-time plant.
