In current studies, non-integer order (NIO) plants with dead time have gained the significant
attention of many researchers in the area of control theory. However, the design methods for …

This paper aims to achieve two goals. First, the tracking problem with a ramp-type setpoint
and disturbance is addressed, where classical methods provide steady-state error. Second …

Controlling delay dominant chemical processes is a challenging control problem. Hence, a
new method for designing a Smith predictor (SP)-based proportional-integral proportional …

Temperature control for fermentation is crucial as it directly affects microorganism growth,
productivity, and metabolic activity. This work proposes a modified fractional order …

Control strategies designed for step signals fail when applied for ramp tracking and ramp
disturbance rejection. Hence, this work presents a novel dual-loop control technique for …

Nonlinearity constraints are inherent in all physical systems and can impact the system
output. The windup issue occurs when actuators reach their limits, causing a disparity …

A tilt integral derivative (TID) controller modifies the proportional integral derivative (PID)
controller in the fractional domain. It converts the proportional gain as a function of frequency …

Unstable chemical processes demonstrate instability in open-loop configurations due to the
presence of poles located in the right-half of the s-plane. Their non-self-regulating nature …

This study proposed an approximated structured fractional order integral-derivative (FOID)
controller to address the limitations of the unstructured fractional controller. Although …

In the realm of discrete-time modeling for gene regulatory networks, significant focus has
been placed on addressing the time lags inherent in the process of DNA transcription to …
