The total cost C T to be minimized will therefore be the integral of an instantaneous cost c(t).
The closed loop behavior of the nominal plant is defined by using frequency specifications, which are combined with an optimization procedure that minimizes the IAE (Integral of Absolute Error) – a cost related to the closed loop time response specifications – in the whole range of plant parameter variations.
All cost prices included in the analyses were valued in terms of integral cost prices [ 16]. in the original database an average of 0.5 cases per item were randomly missing because some patients had failed to answer all questions of a particular questionnaire.
An overview is given of design philosophies named as "traditional" and "modern" design and the various design rules by which the structural behaviour in terms of stiffness, strength and deformation capacity can be predicted, with the aim of reducing the integral costs of steel structures.
All volumes were valued in terms of Dutch integral cost prices at the price level of 2004 (Oostenbrink et al., 2004).
The cost function to be minimized is a linear combination of a time-weighted cumulative term that penalizes the tracking error, that is, an integral of time squared error (ITSE) cost term, and a cumulative term which penalizes the control signal deviations from its steady-state value.
In particular, a formula is derived for computing the gradient of a given integral performance cost with respect to the switching surface parameters.
The first integral measures the value of the end products to consumers, the second and third integrals the cost of production, and the last term the transport cost.
In this work sufficient time-varying conditions were established for assuring local persistent excitation for identification of a large class of nonlinearly parametrized model structures under integral cost functionals of arbitrary degree.
Only after performing such exercises can reliable estimates of integral project costs be obtained.
At last, costs arising from being too ill to perform domestic tasks were evaluated at the price of domestic help at €8,30. a Integral unit cost prices [17].
