This paper presents the design, implementation and validation of real‐time visual servoing tracking control for a ball and plate system. The position of the ball is measured with a machine vision system. The image processing algorithms of the machine vision system are pipelined and implemented on a field programmable gate array (FPGA) device to meet real‐ time co...

This article addresses the design of PID, I-PD and PD-PI controller for the ball and beam system. The ball and beam system, a non linear one, has been linearised around the equilibrium point to obtain the linearised model transfer function. The PID controller has been tuned using ITAE criterion and the same set of parameters has been utilized for designing both the I-PD and PD-PI controller. Th...

There have been several results on the nonlinear control of a ball and beam system. However, the existing methods often consider a simplified model, and particularly they neglect the centrifugal force term. In this paper, we propose a full-model based adaptive state feedback controller with dynamic gain in order to control the ball and beam system using the centrifugal force term. The dynamic g...

In this paper a multistage fuzzy controller is designed and implemented on the ball and beam system which is a well-known benchmark in the control area because of its nonlinear, unstable non-minimum phase behavior. The most important property of the proposed controller is its simplicity whiles it fully mimics human’s actions for controlling this system. In comparison to classical controllers su...

a 45- year old man with a history of aortic valve replacement presented with acute chest pain which was diagnosed to be anterior wall myocardial infarction. he received thrombolytic therapy with streptokinase. echocardiography and fluoroscopy showed normally functioning ball and cage aortic prosthesis. coronary arteriography showed globular filling defect in midportion of left anterior descendi...

The ball-like structures were observed on the PF-1000 device at the shots with the deuterium or neon fi lling and deuterium puffi ng usually outside of the dense-pinched plasma column. The short description of the ball-like structures observed in shot #10080 and #10122 was presented in a paper [1]. In that paper, it was observed that the ball-like structures occurred at the imploding plasma she...
