PID control system analysis, design, and technology [PDF]

open access: yes, 2005
Designing and tuning a proportional-integral-derivative (PID) controller appears to be conceptually intuitive, but can be hard in practice, if multiple (and often conflicting) objectives such as short transient and high stability are to be achieved ...

Mathematical modelling and controller design using electromagnetic techniques for sugar industry process

open access: yesAutomatika, 2021
The design and tuning of controllers for the industrial process is an art, which plays a vital role in many of the process control industries. The industries such as sugar, chemical, paper and other process control-based industries hold the nature of non-

Evolution or Revolution? PIDs for PID Users

open access: yes, 2020
The case for using PIDs extensively and consistently has more or less been made which begs the question as to why they are not implemented as completely as one might wish? The ARDC, through our National Information Infrastructure program, promotes the use of PID’s in the Australian research sector as a mechanism to link research concepts, funding ...

Optimal frequency control in microgrid system using fractional order PID controller using Krill Herd algorithm [PDF]

open access: yes, 2020
This paper investigates the use of fractional order Proportional, Integral and Derivative (FOPID) controllers for the frequency and power regulation in a microgrid power system. The proposed microgrid system composes of renewable energy resources such as

Dynamic optimal operational control for complex systems with nonlinear external loop disturbances

open access: yesAIMS Mathematics, 2022
This paper studies a two-layer control strategy for optimal operational control which is prevalent in industrial production. The upper layer determines and adjusts the target set values, while the lower layer makes the loop output track the target value.

Design and Analysis of AAUSAT Cube Satellite Attitude Determination with PID Algorithms and Orbitron TLE [PDF]

open access: yesINCAS Bulletin, 2023
Satellites are intended to be of massive cost, hard, or hard to keep up and fix in circle. The point of this task is to decide an effective strategy to decide the orbital and heading data for the Nano satellite.
