Turbocharged diesel engines are now being used in every automobile by a lot of automobile manufacturing companies. A turbocharged diesel engine (TDE) equipped with variable geometry turbocharger and exchange gas recirculation is explained in detail. A linear turbocharged diesel engine model is presented and its control techniques are explained in detail. Controllers are designed using the linea...

This research deals to introduce a new method for generalizing the well-famed Quantitative Feedback Theory (QFT) in granting robustness of Feedback linearization on nonlinear systems. In this new scheme, first applying feedback linearization, with selecting operating points in domain of system parameter's variations, nonlinear systems replaced with linear systems, then robust controller is desi...

An unmanned free-swimming submersible (UFSS) is designed to perform certain tasks in water without interposing humans. The vehicle’s control achieved by integrating mathematical (analog) and non-mathematical (embedded) controllers. main goal of integrated controllers overcome the environmental disturbances noise sensor data. These disturbances, as well data, are generated during steering, divin...

The optimal sampling problem is the selection of instants together with control actions such that a given cost function minimized. In this article, we solve for free final time linear quadratic regulator. Each instant computed as minimization maximum eigenvalue formulated at each stage by previously applying dynamic programming. solution provides instants, actions, and in recursive constructive...

The linear quadratic regulator problem is central in optimal control and has been investigated since the very beginning of theory. Nevertheless, when it includes affine state constraints, remains challenging from classical “maximum principle” perspective. In this study we present how matrix-valued reproducing kernels allow for an alternative viewpoint. We show that objective paired with dynamic...

This work presents a control scheme to grid-connected single-phase photovoltaic (PV) system. The considered system has four 250 W solar panels, non-inverting buck-boost DC-DC converter, and DC-AC inverter with an inductor-capacitor-inductor (LCL) filter. aims track operate at the maximum power point (MPP) of PV regulate voltage DC link, supply grid unity factor. To achieve these goals, proposed...
