A Multi-objective, active fuzzy force controller in control of flexible wiper system

Abstract

Chaotic vibration has been identified in the flexible automotive wiper blade at certain wiping speeds. This irregular vibration not only decreases the wiping efficiency, but also degrades the driving comfort. A reliable nonlinear system identification namely nonlinear auto regressive exogenous Elman neural network (NARXENN) was adopted in first stage of this survey to model the flexible dynamics of wiper blade with acquired experimental data. In controller design part, taking into account environmental and external disturbances that cause changes in the dynamic characteristics of the system demanded a robust controller to make a trade off between the worst and best scenario. An active fuzzy force controller (AFLC) supervised by multi objective genetic algorithm (MOGA) is developed to keep both interests of noise and vibration redaction of automobile wiper blade at the reasonable rise time.

A novel hybrid LUS–TLBO optimized fuzzy-PID controller for load frequency control of multi-source power system

“…Similarly the controllers for hydro unit and gas unit have four scaling factors each. Zolfagharian et al [29] have designed a multi-objective genetic algorithm based active fuzzy force controller to reduce noise and vibration of automobile wiper blade. Zolfagharian et al [30] have presented the application of multi-objective genetic algorithm to optimally design a fuzzy-PID controller for reducing the noise level and vibration of wiper system.…”

Numerical Investigations of the Kinetic Behavior of Adhering Droplets on the Inclined Windshield in Airflows

“…Initial approaches to the issue of windshield water contamination brought on by rain concentrated on the continuous optimization of vehicle components to reduce the problem of visual obstruction, including the structure of the wipers [7,8], control strategies [9,10], and the wetting characteristics of the windshield [11][12][13]. These techniques can somewhat lessen the amount of precipitation that accumulates on the windshield but cannot reduce the frequency of raindrop impact.…”

Theoretical analysis on nonlinear vibration of fluid flow in single-walled carbon nanotube

“…Mathematical modeling is a vantage point to reach a solution in an engineering problem, so the accurate modeling of nonlinear engineering problems is an important step to obtain accurate solutions [17][18][19][20][21]. Most differential equations of engineering problems do not have exact analytic solutions, so approximation and numerical methods must be used.…”
