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...

Chemotherapy is a widely used cancer treatment method globally. However, cells can develop resistance towards single-drug-based chemotherapy if it infused for extended periods, resulting in failure many cases. To address this issue, oncologists have progressed using multi-drug (MDC). This considers different drug concentrations treatment, but choosing incorrect adversely affect the patient’s bo...

The approximation of a fractional order PIλDμ-controller transfer function using chain fraction theory is considered. Analytical expressions for the s±α components functions PIλDμ-controllers were obtained through application theory. Graphs transition and frequency characteristics Dμ (α = μ 0.5) Iλ λ −0.5) parts five different decomposition orders analyzed. results showed possibility applying b...

Fractional order control (FOC) has received widespread attention in recent years due to its efficient tuning capacity, intuitive concept, and enough flexibility. Again, FOC are known be robust with the open loop gain particular. However, design of demands knowledge model modified. But on other hand, linear active disturbance (LADRC) technique is free controller. In achieve better tracking perfo...

Fractional calculus has gained increasing attention from researchers because of providing accurate modelling and flexible controller design in control applications. More research to controllers for Order Two-Input Two-Output (FOTITO) systems, which inherently have certain difficulties, is needed when the studies about these applications are considered. In this study, Coefficient Diagram Method ...
