The contrast performance of current extreme adaptive optics (XAO) systems can be improved by adding a second AO correction stage featuring its own wavefront sensor (WFS), deformable mirror (DM), and real-time controller. We develop dynamical model for such cascade (CAO) system with two stages each controlled standard integrator study control properties. how configuration improve an existing wit...

<a name="_Hlk98601430"></a><span lang="EN-US">In this research, a sensor free DC-link voltage controller based multifunctional inverter is proposed for two-stage three-phase grid-connected solar photovoltaic (PV) system. First, the scheme consists of an outer requiring knowledge, has ability to manage power-sharing between PV system and utility grid, second, VSI act as compens...

Multi-link wheeled robots provide interesting opportunities within many areas such as inspection and maintenance of pipes or vents. A key functionality in order to perform such operations, is that the robot can follow a predefined path fast and accurately. In this paper we present an algorithm to learn the path-following behavior for a set of motion primitives. These primitives could then be us...

This paper presents track-following control design, with a new sensitivity shaping technique, for dual-stage servo systems in hard disk drives. The shaping technique simultaneously takes care of both complexity of controllers and robustness, important issues for controller implementation. As dual-stage servo systems, in addition to the conventional voice coil motor, a microactuator at the slide...

designing of a pid controller is a very common method for industrial process control and due to its very simple and efficient function; it is used in a wide variety of industrial applications. pid controller to reduce the steady state error and dynamic response of the system is used. pid controller design is an inevitable problem in setting the coefficients need to try a lot of trial and error,...

Training students in intelligent robotics requires a large investment both in time and cost. Intelligent controller development requires proficiency in many areas including math, programming, electronics. Students that are not patient with themselves can be frustrated by the large learning curve. This frustration increases when the robot equipment used for assignments is not available (broken o...

A novel approach is presented for approximating real continuous functions of many variables using a two-stage neural network technique. In the first stage, a group of Support Vector Machines (SVMs) is involved in approximating the function based on different methods for selecting and transforming the input variables. In the second stage, an SVM is employed to combine the function approximation ...
