Abstract The implementation of image-based phenotyping systems has become an important aspect crop and plant science research which shown tremendous growth over the years. Accurate determination features using images requires stable imaging very precise processing. By installing a camera on mechanical arm driven by motor, maintenance accuracy stability becomes non-trivial. As per state-of-the-a...

this paper presents a new optimization algorithm to design an optimal proportional, integral, derivative (pid) controller in hydro-turbine generator governor for damping output frequency oscillations. in this research, we utilize a stochastic and optimal based pid controller to control frequency-response of the hydro turbine. the proposed algorithm is employed to design an optimal pid controlle...

Gain scheduling (GS) is one of the most popular approaches to nonlinear control design and it is known that GS controllers have a better performance than robust ones. Following the terminology of control engineering, linear parameter-varying (LPV) systems are time-varying plants whose state space matrices are fixed functions of some vector of varying parameters. Our approach is based on conside...

Although many PID tuning approaches are available, it is not easy to find a method that does not require any engineer/operator interference. In this work, we present a fully automated approach for PID tuning based on relay feedback. This method involves sending the relay feedback test data from PLCs (Programmable Logic Controller) into a historian, analyzing the test data using a tuning applica...

In this paper, an attempt is made to apply the African Buffalo Optimization (ABO) to tune the parameters of a PID controller for an effective Automatic Voltage Regulator (AVR). Existing metaheuristic tuning methods have been proven to be quite successful but there were observable areas that need improvements especially in terms of the system's gain overshoot and steady steady state errors. Usin...

<p class="Abstract">Brushless DC motor (BLDC) is one type of electric that widely used, especially in automotive systems. This used as a driving force vehicles. BLDC chosen because it has the characteristics high efficiency, reliability, and wide speed range. Besides, motors require less maintenance can operate quieter than motors. Even though many advantages, its application use vehicles...

Utilization of renewable energy from solar panel systems is increasingly being applied, but until now its utilization has not been maximized. The movement the sun caused by rotation earth and cloudy condition should be taken into account to maximize electrical in panels. In this study, a concept calculate two-axis tracker proposed using combination two controller methods, i.e. Proportional Inte...

Decentralized systems are a subset of distributed systems where multiple authorities control different components and no authority is fully trusted by all. This implies that any component in a decentralized system is potentially adversarial. We revise fifteen years of research on decentralization and privacy, and provide an overview of key systems, as well as key insights for designers of futur...

Decentralization is a major challenge for secure computing. In a decentralized setting, principals are free to distrust each other. The key challenge is to provide support for expressing and enforcing expressive decentralized policies. This paper focuses on declassification policies, i.e., policies for intended information release. We propose a decentralized language-independent framework for e...

The classical multivariable Smith predictor is extended to multivariable nonsquare systems with multiple time delays where the number of process inputs is higher than the process outputs. Pairing for input and output variables is carried out using the block relative gain technique. Simplified decoupling method is applied to design the decouplers. The decoupled processes are modeled as first-ord...
