The inverted pendulum system is a classical control theory benchmark known for its nonlinear and unstable dynamics. This paper presents a comparative study of three advanced control strategies: Linear Quadratic Regulator (LQR), Model Predictive Control (MPC), and Fuzzy Logic Control (FLC) for stabilizing an inverted pendulum system. Each controller is designed to stabilize the pendulum upright while minimizing the cart displacement. Performance is evaluated based on settling time, rise time, steady-state error, and control effort under nominal and perturbed conditions, including varying pendulum mass and initial angle. Results indicate that while LQR offers a fast response, it demands high control energy. MPC ensures precise tracking but is computationally intensive. FLC provides a robust and energy-efficient balance, making it ideal for uncertain environments. 05 30 2025 05 30 2025 27 35 CC-BY-NC-ND 4.0 10.35940/BEIESP.CrossMarkPolicy www.ijitee.org true International Journal of Innovative Technology and Exploring Engineering (IJITEE) Blue Eyes Intelligence Engineering and Sciences Publication (BEIESP) Based on my understanding, this article has no conflicts of interest.
