pushing the boundaries of conventional PID controllers While PID controllers offer excellent performance in steadystate conditions they struggle with Unpredictable disturbances Fluctuations in load friction or environmental factors can significantly disrupt system performance PID controllers often require manual tuning to compensate for these variations leading to timeconsuming adjustments Nonlinear system dynamics Realworld systems often exhibit nonlinear behavior making it difficult to achieve accurate control with linear PID controllers Uncertain operating environments Complex

have severe consequences depending on the application Transparency and accountability The decisionmaking process within the Fuzzy Logic component needs to be transparent and auditable to ensure accountability and prevent unexpected or potentially harmful behaviors Bias and fairness Training data used for Fuzzy Logic rules should be representative of the systems operating environment to avoid
