Abstract: The object of this study is to develop a self-tuning fractional order proportionalintegral-derivative (SFOPID) controller for controlling the mover position of a direct drive linear voice coil motor (VCM) accurately under different operational conditions. The fractional order proportional-integral-derivative (FOPID) controller can improve the control performances of the conventional i...

ریزشبکه‌ها شاخه‌ای از منابع انرژی پراکنده‌اند که بیشتر از انرژی‌های تجدیدپذیر برای تولید توان الکتریکی استفاده ‌می‌کنند و به بار‌های پراکنده در حالت‌های متصل به شبکة سیستم‌های توزیع و منفصل از شبکه خدمات ‌می‌دهند.‌‌‌‌‌‌ به دلیل تغییرات طبیعی تولید توان با انرژی‌های تجدیدپذیر ‌‌و عدم‌قطعیت‌های سیستم قدرت‌‌‌‌‌‌، در این مقاله از کنترل‌کنندۀ PID مرتبه کسری (FOPID) به دلیل عملکرد مقاوم و ساختار سادۀ...

این مقاله روش جدیدی را برای طراحی کنترل‌کننده PID مرتبه کسری (FOPID) به منظور کنترل مبدل بوست ارائه می‌دهد. FOPID یک نوع PID است که مرتبه ترم مشتقی و انتگرالی آن به جای عدد صحیح از مرتبه کسری است و با استفاده از آن می‌توان سیستم را با انعطاف‌پذیری بیشتری کنترل نمود. در این مقاله برای کنترل مبدل بوست از کنترل‌کننده FOPID استفاده شده است. به منظور تعیین پارامترهای کنترل‌کننده FOPID از الگوریتم رق...

In this paper a new method for speed control of BLDC motors is proposed. In this method, fractional order PID (FOPID) is used for control of BLDC motor. In order to determine the parameters of FOPID controller imperialist competitive algorithm (ICA) is employed for its high speed and accurate for solve of optimization problems. In order to verify the performance of proposed controller, some sim...

In this paper we propose a Fractional Order Controller for an under-actuated system (POAC). This system has two degrees-of-freedom and one control input. The model of the system is derived using Euler Lagrange method and the stabilization is achieved with constraints using Fractional Order Controller. To validate the control law, simulation are performed and compared with Integer Order Controll...

This paper presents the application of Fractional Order PID controller as a supplementary controller to improve the dynamics of LFC in multi area deregulated power system. FOPID is a PID controller whose derivative and integral orders are of fractional rather than integer. The extension of derivative and integration order from integer to fractional order provides more flexibility in design of t...

In this paper, Two-Degree-of-Freedom-Fractional Order PID (2-DOF-FOPID) controller is proposed for automatic generation control (AGC) of power systems. Proposed controller is tested for the first time on a three unequal area thermal systems considering reheat turbines and appropriate generation rate constraints (GRCs). The simultaneous optimization of several parameters of the controllers and s...

A Field Programmable Gate Array (FPGA) is proposed to build an Adaptive Neuro Fuzzy Inference System (ANFIS) for controlling a full vehicle nonlinear active suspension system. A Very High speed integrated circuit Hardware Description Language (VHDL) has been used to implement the proposed controller. An optimal Fraction Order PI λ D μ (FOPID) controller is designed for a full vehicle nonlinear ...

Differential Evolution (DE) has recently emerged as a simple yet very powerful technique for real parameter optimization. This article describes an application of DE for the design of Fractional-Order Proportional-Integral-Derivative (FOPID) Controllers involving fractional order integrator and fractional order differentiator. FOPID controllers’ parameters are composed of the proportionality co...
