Improved Linear Active Disturbance Rejection Control for Microgrid Frequency Regulation

The frequency regulation has become one of the major subjects in microgrid power system due to the complexity structure of microgrid. In order to solve this problem, this paper proposes an improved linear active disturbance rejection control algorithm (ILADRC) that can significantly improve system performances through changing feedback control law to reduce the disturbance estimation error of e...

Nonlinear Pid Control of Linear Plants for Improved Disturbance Rejection

A nonlinear PID (NPID) controller for a class of linear plants with output feedback is studied. The controller gains are modulated by the control error and error rate to yield a closed-loop system for improved disturbance rejection. An optimization problem involving constraints written as linear matrix inequalities (LMIs) is solved to compute the controller parameters. A hard disk drive (HDD) c...

Active Disturbance Rejection Control for Web Tension Regulation

A new control method is proposed for tension regulation in a web transport system. It is based on a unique active disturbance rejection control (ADRC) strategy, which actively compensates for dynamic changes in the system, and unpredictable external disturbances. A simulation of an industrial application is used to provide realism. The results show the effectiveness of the proposed tension cont...

PID controller with improved load-disturbance rejection

In this paper a two-degree-of-freedom (2DOF) IMC structure is considered for integrating process with deadtime to achieve improved load-disturbance response along with the set-point response. Set-point controller is designed considering desired speed of response of the closed-loop system. The load-disturbance controller is designed through direct synthesis approach and both the controllers are ...
