Semi-Active Pulse-Switching SSDC Vibration Suppression using Magnetostrictive Materials
One of the best vibration control methods using smart actuators are semi-active approaches which are as strong as active methods and need no external energy supply such as passive ones. Compared with piezoelectric-based, magnetostrictive-based control methods have higher coupling efficiency, higher Curie temperature, higher flexibility to be integrated with curved structures and no depolarizati...
متن کاملSecond Order Sliding Mode Observer-Based Control for Uncertain Nonlinear MEMS Optical Switch
This paper studies theuncertain nonlinear dynamics of a MEMS optical switch addressing electrical, mechanical and optical subsystems. Recently, MEMS optical switch has had significant merits in reliability, control voltage requirements and power consumption. However, an inherent weakness in designing control for such systems is unavailability of switch position information at all times due to t...
متن کاملMaternal Risk Factors Affecting Low Birth Weight in Rafsanjan Township in 2018: A Case Control Study
Background and Objectives: Low birth weight is one of the most widespread public health problems associated with high infant mortality. This study aimed to identify maternal risk factors affecting low birth weight neonates in Rafsanjan hospitals. Materials and Methods: This case-control study consisted of 120 low birth weight infants (less than 2500 grams) as the case group and 120 normal weig...
متن کاملOptimal Sensorless Four Switch Direct Power Control of BLDC Motor
Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...
متن کاملطراحی سوئیچ تمام نوری با استفاده از خاصیت غیر خطی Kerr وDIT با نانو کریستال چهار ترازه
We propose a novel two state and all-optical controllable switch using DIT, Kerr effect and interaction between quantum dots (QD) and quantum electrodynamics cavity (CQED). The two state and all-optical controllable switch is coupled to photonic waveguide from a rapid nonlinear environment (photonic crystal) and CQED. We consider the nano-crystal are doped to crystal photonic cavity as a 4-leve...
