Aderivative-free, delayedweight update lawis developed formodel reference adaptive control of continuous-timernuncertain systems, without assuming the existence of constant ideal weights. Using a Lyapunov–Krasovskiirnfunctional it is proven that the error dynamics are uniformly ultimately bounded, without...
An adaptive control system is disclosed. The control system can control uncertain dynamic systems. The control system can employ one or more derivative-free adaptive control architectures. The control system can further employ one or more derivative-free weight update laws. The derivative-free weight...
In this paper, we propose a descent derivative-free method for solving symmetric nonlinear equations. The method is an extension of the modified Fletcher-R... XL Wang,DH Li - 《Numerical Algebra Control & Optimization》 被引量: 43发表: 2011年 The Adaptive Sampling Gradient Method Optimizing Sm...
6.2.1 PID control Nowadays, proportional-integral-derivative (PID) control has been widely used in practice, owing to its model-free and effective merits. Carrozza et al. adopted a proportional-integral (PI) strategy to achieve stable and accurate grasping force control in biomedical microdevices ...

these therapeutics are complicit with dose limitingnephrotoxicity. The natural polymyxins posses five free amino groups (diaminobutyric acid residues) and a C8–C9 fatty acid side chain and are thus, strongly cationic and lipophilic (amphiphilic).Polymyxin derivativesthat have reduced the size of the ...
In this work, we present noninvasive, derivative-free, easily parallelizable procedures to solve this joint optimization problem. Specifically, we consider Particle Swarm Optimization (PSO), a global stochastic search algorithm; Mesh Adaptive Direct Search (MADS), a local search procedure; and a ...
To determine interstitial fibrosis, a total of 30 areas were ran- domly selected per animal from the free wall and the septum of the LV, and the areas of fibrosis and myocytes was calcu- lated and used for the analysis. To evaluate perivascular fibro- sis, approximately 20 vasculatures ...
, with 67% obtaining a CR and 22% a partial response (PR). A response improvement was again observed in a portion of patients after completing therapy. Median progression-free survival (PFS) was 53.8 months, with 3-year PFS of 87.0% and 3-year overall survival of 100%. Toxicity was ...
The 8-week old male C57BL/6J mice were purchased from the Animal Laboratory Center of Sichuan University (Chengdu, China) and housed in a controlled environment (constant temperature at 20 ± 2°C and humidity at 50–60% with a 12-h light and 12-h dark cycle) and were free access to...
