Abstract
This paper suggests an adaptive control approach using water cycle algorithm optimization method (WCA) modified by a new technique called “Balloon Effect”. The main concept of Balloon Effect is to increase the ability of the WCA to tune individually the gains of the controller online. The proposed technique has been used to tune the gains of PID controller and applied to control both of the load frequency control in micro-grid power system (which minimize the fundamental frequency variations) and the position of armature-controlled DC motor. Digital simulations have been carried out to prove the efficiency of the proposed adaptive controller-based WCA with Balloon Effect. The obtained results showed that the proposed adaptive controller maintains robust performance, and effectively reduces the impact of identified disturbances and uncertainties.
Highlights
Despite modern and intelligent control techniques which appeared during last decades, PID controller acts as a main player to control the industrial and practical process
This paper suggested a modified water cycle algorithm optimization method (WCA) with Balloon Effect, this Balloon Effect (BE) is designed to enable WCA to work individually as an adaptive controller to tune the PID controller, by other way it increases the sensitivity of WCA to system parameters changes and system disturbance
This paper suggests a novel adaptive controller using modified water cycle algorithm that is used individually to tune the gains of the traditional controller parameters
Summary
Despite modern and intelligent control techniques which appeared during last decades, PID controller acts as a main player to control the industrial and practical process. One of the weaknesses of the classic WCA application in the adaptive control problem can be expressed as follows: according to the nominal transfer function of the plant considering no load disturbance, the objective function has been designed. Mohamed et al.: WCA-Based Adaptive Control Approach Using BE: Electrical Systems Applications parameters. It represents the effect of the system changes on the on-time system open loop transfer function, which is similar to the effect of air on balloon size. This paper suggested a modified WCA with Balloon Effect, this Balloon Effect (BE) is designed to enable WCA to work individually as an adaptive controller to tune the PID controller, by other way it increases the sensitivity of WCA to system parameters changes and system disturbance.
