Observer-based anti-windup robust PID controller for performance enhancement of damped outrigger structure

Abstract

This study presents an observer-based anti-windup robust proportional–integral–derivative controller with state estimator method for damped outrigger structure using magneto-rheological damper to mitigate the seismic response. In this approach, full-order Kalman observer is designed for estimating the states of the damped outrigger system from the feedback of the system output with optimum observer gain. However, due to the computational complexity, the integral windup is observed in the loop; therefore, integral anti-windup is introduced for the internal stability in the loop to produce the desired output. The semi-active magneto-rheological damper is integrated with the proposed system, to produce the required force by the system that ranges between the maximum and minimum values as regulated by the voltages produced by the controller in action for every instant of the seismic energy. The proposed strategy is designed in MATLAB and Simulink to find the adequacy of the damped outrigger system in terms of mitigating the following seismic responses like displacement, velocity, and acceleration. The dynamic analysis of the damped outrigger structure with the proposed control strategy shows enhanced performance in reducing the response of the structure as observed in peak response values. The evaluation criteria show a significant reduction in the vibration of the structure.

Kavyashree et al [15] presented an observerand state-estimator-based anti-windup robust proportionalintegral-derivative controller for a damped outrigger structure using a magnetorheological damper to mitigate the seismic response. They designed a full-order Kalman observer to estimate the states of a damped outrigger system based on the feedback of the system output.…”

Secondary Controller for Voltage and Frequency Regulation in an Islanded Microgrid System Based on Anti-Windup Loop

“…As a result, significant error accumulates, causing an overshoot or undershoot in the system. This problem is called wind-up [12]. Some approaches have been proposed to deal with this phenomenon in the PI controller, such as Back-Calculation and Clamping [13].…”

A control system for MR damper-based suspension of front-loaded washing machines featuring magnetic induction coils and phase-lead compensator

“…There have been many controllers proposed for MR fluid devices that can be categorized into three approaches: classic, advanced, and hybrid controllers. The classic control strategies such as sky-hook controller (Kwak et al, 2014; Seong et al, 2011; Talib et al, 2021) and proportional–integral–derivative (PID) controller (Erol et al, 2012; Kavyashree et al, 2022; Oh et al, 2014) can provide favorable output performance, but is short of robustness under exterior disturbance sources and parameter uncertainties. In spite of this shortcoming, the classic methods are commonly adopted in semi-active control systems featuring MR fluid due to their simplicity and low computational cost.…”
