The title of this work is “Arduino Uno Based Maximum Power Point Tracking System by the optimization of solar energy”. This paper’s objective is to have a solar panel outputting its maximum possible power throughout; this occurs when the panel tracks the sun and rotates accordingly, to receive sunlight to the fullest extent always during the day time. This movement is achieved by installing a c...

BACKGROUND The design complexity of critical care ventilators (CCVs) can lead to use errors and patient harm. In this study, we present the results of a comparison of four CCVs from market leaders, using a rigorous methodology for the evaluation of use safety and user experience of medical devices. METHODS We carried out a comparative usability study of four CCVs: Hamilton G5, Puritan Bennett...

In this paper, an adaptive piecewise linear control scheme is proposed for improving the performance and response time of servo mechanical control systems. It is a gain stabilized control technique. No large phase lead compensations or pole zero cancellations are needed for performance improvement. Large gain is used for large tracking error to get fast response. Small gain is used between larg...

Since straightness error of linear motor stage is hardly dependent upon machining accuracy and assembling accuracy, there is limit on maximum realizable accuracy. To cope with this limitation, this paper proposed a servo system to compensate straightness error of a linear motor stage. The servo system is mounted on the slider of the linear motor stage and moves in the direction of the straightn...

An adaptive sliding mode controller (ASMC) based on characteristic model is designed to overcome the detrimental effect of large inertia ratio and large-range varying inertia in high accuracy servo systems. The servo system discrete characteristic model is established and adopted for the controller designed instead of using the traditional mechanism model. The recursive least square (RLS) algor...

The robotics research program at Florida International University develops a broad range of robotic systems with a level of capability and robustness that supports long term, applied field operations. This paper provides insight into the design of a 1-Degree of Freedom (DOF) force-reflecting manual controller (FRMC) for the development of a teleoperation system by reviewing the wave variables t...

This paper poses a number of questions related to the performance and structure of closed-loop visual control, or visual servo, systems. While the fundamentals of visual servo control are well known and systems have been demonstrated for many years, the achieved performance is far less than could be expected. In particular the questions discussed relate to fundamental control system structure, ...

To improve product quality in high-tech industrial fields and in precision product processes, high precision position control systems have been developed. However, high precision position control systems have been faced with a friction problem that exists between the contact surfaces of two materials and produces an obstacle to the precise motion, because the friction is very sensitive to nonli...

The conception of raising dynamic stiffness of electro hydraulic position servo system by flow feedforward compensation is put forward. First, the elementary principle of maintaining piston position unchanged under sudden external force load change by charging additional oil volume is analyzed. Then, a scheme using double servo valves to realize flow feedforward compensation is presented, in wh...

A Concurrent Relay-PID controller (CRPID) for motor position servo systems is proposed in this paper. The proposed controller is composed of a deadband-relay subcontroller and a parallel PID subcontroller. The deadband-relay subcontroller is capable of improving the transient system performance while the PID subcontroller is responsible for near steady state system regulation. Systematic design...
