Frequency control scheme based on the CDM-PID controller for the hybrid microgrid system with stochastic renewable generators

open access: yesAutomatika, 2023
In this paper, we introduce a Coefficient Diagram Method (CDM) to design a conventional PID controller. This controller is used to decrease the frequency fluctuations of a microgrid system composed of two renewable energy sources (WTG and STPG) and four ...

A Coefficient Diagram Method Controller with Backstepping Methodology for Robotic Manipulators

open access: yesJournal of Electrical Engineering, 2015
Abstract A new robust control procedure for robot manipulators is proposed in this paper. Coefficients diagram method controllers CDM and Backstepping methodology are combined to create the novel control law. Two steps of backstepping on the resulting system are used to design a nonlinear CDM-Backstepping controller.

S-domain stability analysis of a turning tool with process damping

open access: yesHeliyon, 2019
This work involved S-domain stability analysis of a turning tool with process damping. Process damping is a phenomenon of dry friction between the tool flank face and workpiece which induces high stability and smoothness at low turning speed.
