A major problem in power systems is achieving a match between the load demand and generation demand, where security, dependability, quality are critical factors that need to be provided producers. This paper proposes proportional–integral–derivative (PID) controller optimally designed using novel artificial rabbits algorithm (ARA) for frequency control (LFC) multi-area (MAPSs) of two-area non-r...

This paper suggests to replace PIs and PIDs, which play a key role in control engineering, by intelligent Proportional-Derivative feedback loops, or iPDs, are derived from model-free control. standpoint is enhanced laboratory experiment.

In this paper, integral plus double derivative (IDD) in coordination with Thyristor Controlled Phase Shifter (TCPS) is applied for the first time in automatic generation control (AGC) system. Comparative studies on the performance of different classical controllers viz. integral (I), proportional plus integral (PI), proportional plus integral plus derivative (PID) and integral plus double deriv...

In this paper a procedure to evaluate and redesign simplified dynamic decouplers using relay-based experiment is applied to a TITO laboratory-scale thermal process. This procedures was originally proposed in (Acioli Júnior and Barros, 2011). The aim of the procedure is to reach effective decoupling at frequencies of interest for control purposes. Keywords— Decoupling Control, Simplified Decoupl...

Automatic Generation Control (AGC); Boiler dynamics; Generation Rate Constraint (GRC); Governor dead band; Proportional Integral Derivative (PID) controller; Differential Evolution (DE) algorithm Abstract This paper presents the design and performance analysis of Differential Evolution (DE) algorithm based Proportional–Integral (PI) and Proportional–Integral–Derivative (PID) controllers for Aut...

Even though employed widely in industrial practice, the popular proportional– integral–derivative (PID) controller has weaknesses that limit its achievable performance. In this paper, an alternative control scheme that combines the simplicity of the PID controller with the versatility of model predictive control is presented. The result is a controller that combines the time-delay compensation ...

In this paper, we propose an efficient control scheme for active queue management (AQM) supporting TCP flows. The proposed controller consists of two parts: a rate controller and a queue size controller. The rate controller is a proportional-integral (PI) controller, which improves the response to dynamic traffic variation and keeps the packet arrival rate around the link capacity. The queue si...

In this paper, a new sensorless model reference adaptive method is used for direct control of active and reactive power of the doubly fed induction generator (DFIG). In order to estimate the rotor speed, a high frequency signal injection scheme is implemented. In this study, to improve the accuracy of speed estimation, two methods are suggested. First, the coefficients of proportional-integral ...

Abstract: Grass is one of the plants that live on God's earth, even grass also written in Al-quran. currently a pest for plants, so sometimes to minimize growth, many farmers or people eradicate by cutting it poisoning grass. Each method used has its own risk work accidents, such as using poison can experience insecticide poisoning. To anticipate this, remotecontrol robot sprays automatic PID d...
