A frequency response based adaptive control scheme with robust frequency domain specifications for industrial center-driven web winders is presented in this paper. The adaptive control scheme consists of: 1) a self-tuning initialization, 2) an adaptive control, with robust specifications, based on the transfer function estimation from the frequency response, and 3) supervisory monitoring and co...

where x ∈ R is represents the variables, c ∈ R defines the objective function, and A ∈ Rm×n and b ∈ R define the constraints. The above form is fairly general; one can model various types of constraints in this form. For example, a constraint 〈a1, x〉 ≥ b1 can be written as 〈−a1, x〉 ≤ −b1. Or, a constraint 〈a1, x〉 = b1 can be written as 〈a1, x〉 ≤ b1 and 〈−a1, x〉 ≤ −b1. The objective function can...

in this paper, we consider admissible estimation of the parameter ?r in the gamma distribution with truncated parameter space under entropy loss function. we obtain the classes of admissible estimators. the result can be applied to estimation of parameters in the normal, lognormal, pareto, generalized gamma, generalized laplace and other distributions.

Let X be a random variable from a normal distribution with unknown mean θ and known variance σ2. In many practical situations, θ is known in advance to lie in an interval, say [−m,m], for some m > 0. As the usual estimator of θ, i.e., X under the LINEX loss function is inadmissible, finding some competitors for X becomes worthwhile. The only study in the literature considered the problem of min...
