Lidocaine is a drug that blocks the sodium channel in a pH, frequency and concentration dependent manner. In this work, we have used a mathematical model of lidocaine developed by our group and incorporated it into the Luo Rudy model of ventricular action potential. We have studied the action of lidocaine on the sodium current (I Na ), maximum upstroke velocity (dV/dt) and conduction velocity (CV) in ischemic tissue. Additionally, we measured the block window (BW) in different concentrations of drug .Our results show that 100 mumol/L of lidocaine under simulated acute ischemic conditions reduces the I Na , dV/dt and CV a 42%, 41% and 24% in the normal zone (cell 54), respectively while in the border zone (cell 94) the decreased was 37%; 44% and 18% for the same parameters. Finally, we have found that lidocaine diminished the BW, thus the drug tends to eliminate the UDB.

Robust LQR via Bounded Data Uncertainties 9

Robust LQR via Bounded Data Uncertainties

2007 9th European control Conference, ECC 2007

作者： Ramos, C. Martinez, M. Sanchis, J. Salcedo, J.V. Predictive Control and Heuristic Optimization Group Department of Systems Engineering and Control Polytechnic University of Valencia Spain

This work presents the tuning of a Linear Quadratic Regulator (LQR) via the Bounded Data Uncertainties (BDU) method in order to improve the system robustness. The BDU method considers models with bounded uncertainties and it is stated as a Min-Max problem where a solution which performs 'best' in the worst-possible scenario is sought. So a new guided way of tuning the LQR is offered, which takes into account the uncertainties bounds, and it results in the modification of the recursive Riccati equation. The application to multidimensional systems is not trivial due to the fact that the problem presents the form of a Two-Point Boundary Value Problem (TPBVP) and it is solved iteratively. © 2007 EUCA.

Genetic algorithm in the optimization of the acoustic attenuation systems

It is well known that Genetic Algorithms (GA) is an optimization method which can be used in problems where the traditional optimization techniques are difficult to be applied. Sonic Crystals (SC) are periodic structures that present ranges of sound frequencies related with the periodicity of the structure, where the sound propagation is forbidden. This means that in the acoustic spectrum there are ranges of frequencies with high acoustic attenuation. This attenuation can be improved producing vacancies in the structure. In this paper we use a parallel implementation of a GA to optimize those structures, by means of the creation of vacancies in a starting SC, in order to obtain the best acoustic attenuation in a predetermined range of frequencies. The cost function used in CA is based on the Multiple Scattering Theory (MST), which is a self consistent method for calculating acoustic pressure in SCs. As a final result we achieve a quasi ordered structures that presents a high acoustic attenuation in a predetermined range of frequencies, independent of the periodicity of the SC.

Lidocaine is a class I antiarrhytmic drug that blocks the sodium channels. This drug is a tertiary amine and exists as an uncharged free amine and cationic protonated form at physiologic pH. Experimental data have shown that the rate of development and recovery of block is slowed at low pH. In this work, a mathematical model of lidocaine effects has been developed. This model has been incorporated to the Luo Rudy model of guinea pig ventricular action potential and we studied the effect of lidocaine on maximum upstroke velocity (dV/dt), action potential duration (APD), conduction velocity (CV) and effective refractory period (ERP) for different values of pH and concentrations of lidocaine. This study demonstrates that 50 mumol/L of lidocaine reduces the dV/dt 36% and 71% as well as the CV a 8% and 17% for pH 7.4 and 6.4 respectively, while the ERP was increased 1.8% and 0.6% for pH of 7.4 and 6.4. The APD does not change when pH was modulated.

Lidocaine is used as an antiarrhythmic drug, its effectiveness is based on its ability to induce usedependent block of cardiac sodium channels. This drug has an effect on conduction velocity (CV) and effective refractory period (ERP). Changes in CV and ERP could have an important role in the induction or suppression of reentrant circuits. We have studied the effect of lidocaine on CV, ERP and the characteristics of reentry conduction induced in regional ischemic tissue by computer simulations. The bi-dimensional tissue includes an ischemic zone that corresponds to 9 minutes of ischemia. This study demonstrates that the lidocaine reduces the CV 40% and 50% and prolongs of ERP 5% and 14% for 50 and 100 ?M of lidocaine respectively. As well as, lidocaine can depress 20% and 60% the window vulnerable respectively.

This work presents a powerful and flexible alternative for tuning PID controllers using Genetic Algorithms. The potential of this technique is shown using non-linear process models and a reference trajectory. Flexibility is demonstrated by showing how to tune an optimal PID in various situations: model errors, noisy input, IAE minimization, and following a reference models, etc. These problems are solved by changing the minimization index.

The purpose of this paper is to describe the implementation of a hierarchical distributed control system for a chemical pilot plant using industrial standard components. The control system consists of three components: regulatory control (mainly PID controllers), multivariable control (Dynamic Matrix control controller) and the optimization and economic layer (Linear Programming). This work also includes details of the implementation tools: PROFIBUS, Lab VIEW and data acquisition modules. The paper concludes with two possible solutions that deal with plants with integral behaviour. Copyright © 2002 IFAC.

ISBN: (纸本)9783902661746

This paper presents a modification to the generalized predictive control algorithm which guarantees closed-loop stability. The GPC controller is designed using a terminal equality constraint. The available degrees of freedom are presented to the designer as parameters called principal components. This components can be left or removed from the solution to get different performances. Two methods to select the degrees of freedom are presented based on percentage of index minimized and control effort applied to the process respectively. This methods can be an alternative to the empirical selection of the weighting control factor λ. Copyright © 2002 IFAC.
