Development of characteristic equations and robust stability analysis for SISO move suppressed and shifted DMC
New controller and closed loop transfer functions for move suppressed and shifted dynamic matrix control were derived in order to compare the controller robustness on several plants as a function of tuning parameters and ... 
Development of characteristic equations and robust stability analysis for MIMO move suppressed and shifted DMC
Discretetime controller and closedloop transfer functions were developed for move suppressed and the recently formulated mshifted multipleinputmultipleoutput (MIMO) dynamic matrix control (DMC). Using these transfer ... 
PID gain scheduling using fuzzy logic
A simple, yet robust and stable alternative to proportional, integral, derivative (PID) gain scheduling is developed using fuzzy logic. This fuzzy gain scheduling allows simple online duplication of PID control and the ... 
The LorenzKrishnamurthy slow manifold
The authors scale the fivemode model introduced by Lorenz and Krishnamurthy and show how explicit solutions may be obtained in the limit of small Rossby number by using the method of multiple scales. They thus obtain a ... 
Competition model for aperiodic stochastic resonance in a FitzhughNagumo model of cardiac sensory neurons
A model is presented to access the cause and effect between noisy threshold inputs and the average firing rate generated by neuron. The neural control in the heart in aperiodic stochastic resonance (ASR) was partially ... 
SISO extended predictive control  Formulation and the basic algorithm
A new predictive controller is developed that represents a significant change from conventional model predictive control. The method termed extended predictive control (EPC) uses one tuning parameter, the condition number ... 
On simplified predictive control as a generalization of leastsquares dynamic matrix control
Simplified predictive control (SPC) of a singleinput singleoutput control scheme is compared to the more sophisticated, leastsquares formulation of dynamic matrix control (DMC) and its movesuppressed variant (movesuppressed ... 
An asymptotic solution for evaluation of stresses in balanced and unbalanced adhesively bonded joints
Adhesively bonding is one of the most commonly and widely used joining methods in various engineering applications. Many fiberreinforced plastic (FRP) structural components nowadays are joined by adhesives. As a result ... 
Online optimization of fuzzyPID control of a thermal process
A constrained optimization of a simple fuzzyPID (PIDâ€”proportional integral derivative) system is designed for the online improvement of PID control performance during productive control runs. The cost function design ... 
Risk aversion predictive control
A qualitycontrolled predictive control method, suitable for control of fast, remote systems subject to significant communication delays, is developed. Each move is quality controlled in that it independently satisfies a ... 
"Smart" baroreception along the aortic arch, with reference to essential hypertension
An arterial model was used to show that the cumulative effects of wave reflections have a surprisingly pronounced effect on the pressure distribution in the root segment of the tree. Global arterial conditions play a role ... 
A continuous analysis of multiinput, multioutput predictive control
A continuous formulation and method of analysis is constructed for multiinput, multioutput (MIMO) predictive control and used to compare Dynamic Matrix Control (DMC) with Simplified Predictive Control (SPC). Approximate ... 
Exponential asymptotics with a small exponent
Analytic and numerical solutions are considered to a simple model problem which contains a surprisingly complicated solution structure. Asymptotic solutions are sought when a parameter that appears as an exponent in the ... 
KLTBased quality controlled compression of singlelead ECG
An electrocardiogram (ECG) compression algorithm based on a combination of the KarhunenLoeve transform (KLT) and multirate sampling is introduced. The use of multirate sampling reduces KLT computational times to those ... 
An alternate algorithm for computing Adomian polynomials in special cases
An alternate algorithm for computing Adomian polynomials in special cases was introduced. The algorithm could be extended for calculating Adomian polynomials in several variables. Analysis showed that this algorithm does ... 
Mechanism of smart baroreception in the aortic arch
A mechanism is proposed by which the patch of baroreceptors along the inner curvature of the arch of the aorta can sense hemodynamic events occurring downstream from the aortic arch, in the periphery of the arterial tree. ... 
Control of cardiac function and noise from a decaying power spectrum
The transduction capability of cardiac affected neurons situated to the heart to control cardiac function was described. It was observed that the through in situ cardiac afferent activity shows evidence of independent and ... 
Multiple scales analysis of water hammer attenuation
A multiple scales analysis is used to construct a uniformly accurate approximation to water hammer pressure wave attenuation that is initiated by a sudden valve opening. The method of analysis is well suited to the study ... 
Small exponent asymptotics
We study the surprisingly complicated asymptotic character of a simple firstorder differential equation, which involves a term with a low exponent of the dependent variable. While numerical solutions and straightforward ... 
Matched asymptotic expansions of unbalanced adhesive joints
A matched asymptotic expansion analysis is used to determine the dependence of shear stress boundary layer thickness on adhesive properties in unbalanced singlelap joints. A uniformly accurate expansion of shear stress, ...
