PID Controller Optimized by Bird Mating Optimizer for Vibration Control of Horizontal Flexible Plate

The flexible structure offers various advantages such as being lightweight, efficient, fast system response, and low energy consumption. However, the light characteristic of the structure leads to excessive vibration, which can lead to system failure. Thus, eliminating vibration from external sources on the horizontal flexible plate structure is compulsory to preserve the performance and lengthen the system's life. To overcome these drawbacks, this project aims to develop an intelligent vibration controller based on bird mating optimizer into a PID controller for vibration cancelation purposes. Bird mating optimizer is known as a new metaheuristic algorithm that was initially proposed to solve ongoing optimization problems with an auspicious performance inspired by the intelligent mating behavior of birds. This algorithm is aimed to find an optimal value for PID controller parameters. The controller is developed using active vibration control technique in simulation environment, and the performance of the proposed controller is compared with classic Ziegler–Nichols tuning approach. It is indicated that, the PID controller tuned bird mating optimizer can outperform the PID tuned by Ziegler–Nichols by achieving the highest attenuation at the first mode of vibration with 27.20 dB attenuation using single sinusoidal disturbance, equivalent to 26.29% of vibration reduction.
