Interacting The highest storage capacity of a circular tank makes it popular in process industries. Because the varying surface area cross-sections tank, this two-tank level system has nonlinear characteristics. Controlling flow rate liquid is one most difficult challenges production process. This proposed effort critical preventing time delays and errors by managing fluid level. Several schola...

Application of fractional order PID (FOPID) controller to an automatic voltage regulator (AVR) is presented and studied in this paper. An FOPID is a PID whose derivative and integral orders are fractional numbers rather than integers. Design stage of such a controller consists of determining five parameters. This paper employs particle swarm optimization (PSO) algorithm to carry out the aforeme...

The issues of stochastically varying network delays and packet dropouts in Networked Control System (NCS) applications have been simultaneously addressed by time domain optimal tuning of fractional order (FO) PID controllers. Different variants of evolutionary algorithms are used for the tuning process and their performances are compared. Also the effectiveness of the fractional order PI(λ)D(μ)...

This paper presents the implementation of Fractional Order PID controller as a supplementary controller to improve the dynamics of Load Frequency Control in an interconnected Power System. FOPID is a PID controller whose integral and derivative orders are of non-integer rather than integer. The extension of integration and derivative order from integer to fractional order provides more flexibil...

Differential equations with fractional-order derivatives, e.g., the “one-half” derivative, have a long history in mathematics, but have not yet attained mainstream use in engineering and applied science. While applications do exist in modeling specific phenomena such as visco-elasticity and other types of difficult-to-model phenomena, and extensions to control such as in fractional-order PID do...
