[ 1 ] - ارائه الگوریتمی ترکیبی برای شبیه‌سازی برش بافت نرم با استفاده از روش اجزای محدود

شبیه‌‌سازی بی‌درنگ برای نشان دادن رفتار واقعی بافت نرم به مدل‌های بیومکانیک دقیقی نیاز دارد که دارای محاسبات سریع باشد. این مدل‌ها در خدمت کاربردهایی از جمله تشخیص پزشکی، برنامه‌ریزی و آموزش جراحی است. یکی از چالش‌ها در شبیه‌سازی عمل جراحی، برش بافت نرم است که به تغییرات ساختار هندسی و مش‌بندی مجدد عناصر در زمان بصورت آنی نیاز دار...

[ 2 ] - Adaptive Control Strategy for a Bilateral Tele- Surgery System Interacting with Active Soft Tissues

In this paper, the problem of control and stabilization of a bilateral tele-surgery roboticsystem in interaction with an active soft tissue is considered. To the best of the authors’ knowledge, theprevious works did not consider a realistic model for a moving soft tissue like heart tissue in beating heartsurgery. Here, a new model is proposed to indicate significant characteristics of a moving ...

[ 3 ] - Output Consensus Control of Nonlinear Non-minimum Phase Multi-agent Systems Using Output Redefinition Method

This paper concerns the problem of output consensus in nonlinear non-minimum phase systems. The main contribution of the paper is to guarantee achieving consensus in the presence of unstable zero dynamics. To achieve this goal, an output redefinition method is proposed. The new outputs of agents are functions of original outputs and internal states and defined such that the dynamics of agents a...

[ 4 ] - Design of Nonlinear Robust Controller and Observer for Control of a Flexible Spacecraft

Two robust nonlinear controllers along with a nonlinear observer have been developed in this study to control a 1D nonlinear flexible spacecraft. The first controller is based on dynamic inversion, while the second one is composed of dynamic inversion and µ-synthesis controllers. The extension of dynamic inversion approach to flexible spacecraft is impeded by the non-minimum phase characteristi...

[ 5 ] - Optimal characteristics determination of engine mounting system using TRA mode decoupling with emphasis on frequency responses

It is possible to improve vehicle vibration by tuning the parameters of engine mounting system. By optimization of mount characteristics or finding the optimal position of mounts, vibration of the engine and transmitted force from the engine to the chassis can be reduced. This paper examines the optimization of 6-degree-of-freedom engine mounting system based on torque roll axis (TRA) mode deco...

[ 6 ] - کنترل ماهواره با رویکرد کنترل پیش‌بین و با استفاده از توابع لاگر

In this paper a Model Predictive Method based controller is proposed to control a satellite. Model Predictive Control (MPC) has been well known as a practical control method for various systems in industry. A problem with this method is its computational effort and time consuming. To reduce computational load Laguerre functions have been proposed in this literature. Simulation results are...
