This paper presents a comparative study of different control design methods applied to a nuclear reactor model. A nuclear reactor temperature controller is designed using the H-infinity (H∞) control. This advanced controller is compared with a conventional Proportional–Integral–Derivative controller (PID) controller and a traditional optimal controller design using Linear Quadratic Gaussian (LQ...

Unmanned aerial vehicles (UAVs), particularly quadcopters, have several medical, agriculture, surveillance, and security applications. However, the use of this innovative technology for civilian applications is still very limited in low-income countries due to high cost, whereas low-cost controllers available market are often tuned using hit trial approach specific This paper addresses issue pr...

This paper presents the use of angular position control approaches for a flexible robot manipulator with disturbances effect in the dynamic system. Delayed Feedback Signal (DFS), Linear Quadratic Regulator (LQR) and Proportional-Derivative (PD) controller are the techniques used in this investigation to actively control the vibrations of flexible structure. A constrained planar single-link flex...

Due to today’s technological development and information progress, an increasing number of physical systems have become interconnected linked together through communication networks, thus resulting in Cyber-Physical Systems (CPSs). Continuous manufacturing, which involves the manufacture products without interruption, has increasingly important many industries, including pharmaceutical chemical...

Abstract One of the characteristics a robust power grid is minimal variations in its frequency to load change or loss generating unit(s). From perspective optimal control theory, issue context interconnected functioning systems investigated this work, and novel controller proposed for single area isolated network. This novelty incorporates all primary solutions that are based on mixture designs...

Brushless DC motors play a vital role as workhorse in many applications, especially home appliances. In the competitive world of day, brushless motor is wise choice for applications because its high power density, simple driving circuit, and efficiency. Accordingly, demonstrating feasibility new controller on this type has undoubtedly paramount importance. Two methods speed controllers, namely ...

This paper deals with the study and comparison of passive and active landing gear system of  the aircraft and dynamic responses due to runway irregularities while the aircraft is taxying. The dynamic load and vibration caused by the unevenness of runway will result in airframe fatigue, discomfort of passengers and the reduction of the pilot’s ability to control the aircraft. One of the objectiv...

The present study uses linear quadratic regulator (LQR) theory to control a vibratory system modeled by fractional-order differential equation. First, as an example of such system, viscoelastically damped structure is selected. Second, LQR designed for in which terms are contained the equation motion. An iteration-based method solving algebraic Riccati proposed order obtain feedback gains LQR. ...
