Parametric Modelling of Flexible Plate Structures Using Ant Colony Optimization
نویسنده
چکیده
Background: This paper presents parametric modelling of flexible plate structures using ant colony optimization (ACO). The global optimization technique of ACO is utilized to obtain a dynamic model of a flexible plate structure based on one-step-ahead (OSA) prediction. Objective: The structure is subjected to three different disturbance signal types, namely random, pseudo random binary sequence (PRBS), and finite duration step. The fitness function for the ACO optimization is the mean-squared error (MSE) between the measured and estimated outputs of the plate. Results: The validation of the algorithm is presented in both time and frequency domains. The developed ACO modelling approach will be used for active vibration control systems design and development in future work. Conclusion The performance of ACO2 has been shown to outperform ACO1 in minimizing the prediction error, resulting in a good level of accuracy of the estimated model.
