The paper discusses the stability and robustness of proportional-integral (PI), proportional-integral-derivative (PID), proportional-integral-derivative-accelerative (PIDA) controller for integral-plus-dead-time (IPDT) plants. To enable implementation measurement noise attenuation, binomial low-pass filters are added to traditional design controllers with ideal transfer functions, impact on rob...

Departing from analyzing a general input-saturated second-order system, Lyapunov-based constructive procedure for the output-feedback stabilization of constantly perturbed DC-DC buck power converter is presented. The proposed scheme also incorporates ?-? modulator. obtained control developed in two parts: proportional-integral-type family algorithms devoted to regulating uncertain system by usi...

Power Factor Correction (PFC) provides well-known benefits to electric power systems. These benefits include power factor correction, poor power factor penalty utility bill reductions, voltage support, release of system capacity, and reduced system losses. The performance of fuzzy logic controller only depends on the selection of membership function and Inference of fuzzy rules, fuzzy logic con...

Functional Electrical Stimulation is a promising approach to treat patients by stimulating the peripheral nerves and their corresponding motor neurons using electrical current. This technique helps maintain muscle mass and promote blood flow in the absence of a functioning nervous system. The goal of this work is to control muscle contractions from FES via three different algorithms and assess ...

-This paper is describing the recently introduced proportional-resonant (PR) controllers and their suitability for grid-connected converters current control. It is shown that the known shortcomings associated with PI controllers like steady-state error for single-phase converters and the need of decoupling for three-phase converters can be alleviated. Additionally, selective harmonic compensati...

In this paper, a real-time capable reference governor superordinate model predictive controller (RG-MPC) is developed for fuel cell (FC) control suitable automotive application. The RG-MPC provides trajectories the subordinate proportional-integral (PI) controllers, which act directly on FC system. Antiwindup and decoupling schemes, are common problems in multivariable PI control, unnecessary, ...

This research aims to address the issue of controlling a multi-span web transport system by an automatic tuning of the PI controllers parameters. The use of multi-span web transport systems often requires dedicating a particular effort for defining a control system able to protect the integrity of the web. The possibility of using PI controllers for each section is attractive considering that a...
