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...

The accurate model-based servo-control of wheeled mobile robots (WMRs) relies upon the formulation of realistic kinematic and dynamic models. We* identify six special WMR characteristics (closed-chains, hig her-pair joints, unactuated and unsensed joints, friction, and pulse-width modulation) that require methodologies for modeling and control beyond those conventionally applied to stationary m...

The increase in aerial storage capacities of future magnetic hard disk drives has fostered the use of dual-stage actuators for high track density data recording. In a hard disk drive with a dual-stage actuator the standard rotary actuation of the voice coil motor is combined with an additional micro or milli actuation to accomplish high-bandwidth and highly accurate track following. In order to...

To achieve the high precision required in future contouring machining applications. accurate servo-controllers for the feed drives are needed. For this purpose conventional P controllers. which are utilized on many CNC systems, are not adequate. and more advanced control algorithms must be implemented. This paper summarizes existing servo-controllers for contouring applications and presents an ...

− One of the recent approaches to test A/D converter performance is the so-called Servo-Loop Method. This method is aimed at the non-linearity extraction of static ADC transfer curve. In this paper, we prove an advanced Servo-Loop version focusing on behavioral and transistorlevel example of the Residual Signed Digit (RSD) cyclic A/D converter design. The background of the considered Servo-Loop...

In this paper, based on feedback linearization control method and using a special PI (propotational integrator) regulator (IP) in combination with a feed-forward controller, a three-phase induction servo-drive is speed controlled. First, an observer is employed to estimate the rotor d and q axis flux components. Then, two input-output state variables are introduced to control the dynamics of to...

This work presents some numerical simulations, performed using AMESim software, for a system composed by two redundant servo-actuators. Certain operating conditions are taken into account these electro-hydrostatic servo-actuators, which coupled to the command surface (aileron) of transport aircraft. We first considered situation slight asymmetries in construction then one servo-actuator fails a...

We describe a general purpose digital servo optimized for feedback control of lasers in atomic, molecular, and optical physics experiments. The servo is capable of feedback bandwidths up to roughly 1 MHz (limited by the 320 ns total latency); loop filter shapes up to fifth order; multiple-input, multiple-output control; and automatic lock acquisition. The configuration of the servo is controlle...

Servo-actuation system is one of the key executing subsystems of the flight control system of an aircraft. With the development of fly-by-wire control systems, redundant servo-actuation systems have been extensively applied. A servo-actuation system has a long life and high reliability, which results in the lack of failure information. In the mean time, available data is insufficient and imprec...
