Robust stability of multi-loop continuous time self-tuning
controllers.
International Journal of Adaptive Control and Signal
Processing, 4(5):359--382, 1990.

DOI ]
The results of an earlier paper concerning global robustness of single-loop self-tuning controllers are extended to include multiple self-tuning controllers operating in a multiple-interacting-loop environment. The robust stability is shown to depend on the singular value loci of a certain transfer function matrix. The need for control weighting to ensure global robust stability is emphasized.

Stochastic approximation and multilayer perceptrons: The gain
back-propagation algorithm.
Complex System Journal, 4:51--74, 1990.
[ bib ]
A standard general algorithm, the stochastic approximation algorithm of Albert and Gardner [1], is applied in a new context to compute the weights of a multilayer perceptron network. This leads to a new algorithm, the gain backpropagation algorithm, which is related to, but significantly different from, the standard backpropagation algorithm [2]. Some simulation examples show the potential and limitations of the proposed approach and provide comparisons with the conventional backpropagation algorithm. |
