Quadrotor control has been noted for its trouble as the consequence of the high maneuverability, system nonlinearity and strongly coupled multivariable. This paper deals with the simulation depend on proposed controller of a quadrotor that can overcome this trouble. The mathematical model of quadrotor is determined using a Newton-Euler formulation. Fractional Order Proportional Integral Derivat...
This paper presents a practical implementation for a new formula of nonlinear PID (NPID) control. The purpose of the controller is to accurately trace a preselected position reference of one stage servomechanism system. The possibility of developing a transfer function model for experimental setup is elusive because of the lack of system data. So, the identified model has been developed via gat...
Background & Aims: The aim of the present study was to find whether prone position is one of the symptoms of childhood gastroesophageal reflux disease or not. Method: In this prospective case-control study, 200 children with gastroesophgeal reflux disease (case group) and 210 healthy children (control group) were studied between 21 march 2009 and 21 march 2011. Data gathering was performed by a...
For the control of dynamic systems such as an Electro-Hydraulic Actuator (EHA), there is a need to optimize based on simulations, since prototype or physical system usually not available during design. In consequence, no identification can be performed. Therefore, it unclear how well simulation model EHA used for multicriteria optimization position due uncertain quality. To evaluate suitability...
