Design of PI Controllers for Hydraulic Control Systems [PDF]
Mathematical Problems in Engineering, 2013 The paper proposes a procedure for design of PI controllers for hydraulic systems with long transmission lines which are described by models of high order. Design is based on the combination of the IE criterion and engineering specifications (settling time and relative stability) as well as on the application ofD-decomposition.

Nonlinear PI control for variable pitch wind turbine [PDF]
, 2016 Wind turbine uses a pitch angle controller to reduce the power captured above the rated wind speed and release the mechanical stress of the drive train. This paper investigates a nonlinear PI (N-PI) based pitch angle controller, by designing an extended ...

Brushless DC Motor Speed Control using both PI Controller and Fuzzy PI Controller
International Journal of Computer Applications, 2015 Brushless DC (BLDC) motors are one of the most interesting motors, not only because of their efficiency, and torque characteristics, but also because they have the advantages of being a direct current (DC) supplied, but eliminating the disadvantages of using Brushes.

Direct power control of SRG‐based WECSs using optimised fractional‐order PI controller
IET electric power applications, 2020 This study introduces two fractional-order proportional–integral (FOPI) controllers optimised by harmony search (HS) optimisation algorithm, for direct power control of switched reluctance generator (SRG) through regulating the off-delay angle of the ...

Fractional order PI λD µA controller design based on Bode’s ideal function [PDF]
Archives of Control Sciences, 2023 The fractional order proportional, integral, derivative and acceleration (PI λD µA) controller is an extension of the classical PIDA controller with real rather than integer integration action order λ and differentiation action order µ.

IMPROVED PI CONTROL VIA DYNAMIC INVERSION [PDF]
IFAC Proceedings Volumes, 2002 Abstract In this paper we present a new design methodology to achieve high performances in the set point following task by means of a standard Proportional-Integral (PI) controller. In particular, a dynamic inversion procedure is adopted to synthesize a suitable command input to the closed-loop control system.

IET Generation, Transmission & Distribution, 2021 An efficient control strategy for two connected microgrids (MGs) is proposed to ensure stable and economic operation. One of the most important means of improving energy efficiency is to achieve the best response for sudden and stochastic disturbances to
